Kernel 5.3.1 and bluetooth #27

Open Bahir opened 5 years ago

Bahir commented 5 years ago

Board: BPI M2 Zero.

I'm trying to setup bluetooth. The same command worked fine with 4.20.17

brcm_patchram_plus -d --patchram /lib/firmware/ap6212/bcm43438a1.hcd --enable_hci --bd_addr b8:27:eb:b7:f9:60 --no2bytes --tosleep 5000 /dev/ttyS1

With 5.3.1 it produced infinite output

writing 01 03 0c 00 writing 01 03 0c 00 writing 01 03 0c 00 writing 01 03 0c 00 writing 01 03 0c 00

And is not finished with "Done setting line discpline"

I will have a look at it when possible. I think brcm_patchram_plus should not be needed or dtb is with the wrong configuration.

avafinger commented 5 years ago

ok, i just gave it a new try, firmware (bt) is missing for the mainline and not to mention that HDMI is broken. I will need more time to find the fix In case you want to search for the bt firmware and put it in the right place, attached is the correct BT dtb configuration. (but HDMI is broken).

bpi-m2-zero-v4.dtb_5.3.1.tar.gz copy it to /boot and overwrite the old dtb.

Bluetooth and HDMI fixed. No need to patchram for 5.3.1. I will push the changes asap.

Here is the fix: https://github.com/avafinger/bananapi-zero-ubuntu-base-minimal/releases/tag/v2.2

Thank you all is good except...

bluetoothd: Can't open input device: No such file or directory (2)
bluetoothd: AVRCP: failed to init uinput for 00:16:44:FD:6B:A0

Looks like uinput kernel module missing.

I have played with BT and unfortunately, there is some issue. I think we have to use the patchram, the old way.

Here is my failed attempt to connect to a JBL speaker and Phone:

Mine is good with connection and pairing but I can't make it work with sound playing.

So, all seems OK in logs but... But, when I try to play something via this BT connection I either receive broken sound in headset (it is what expected but very dirty one) or connection is interrupted.

root@bpi-m2z:~# paplay /usr/share/sounds/alsa/Front_Center.wav
Connection failure: Connection terminated
Stream error: Connection terminated

And pulseaudio process also goes down.

Also, I noticed that when I activate something with BT (pulseaduio, bluetoothctl) the WIFI connection sometimes interrupts responding (strange delays when i type in ssh console). And sometimes I need to restart ssh session at all after I activated BT.

And, the same is for 4.20.17 and for 5.3.1 so I have an idea that something is wrong with firmware or sdio.txt.

Here are mine I use.

Interesting. I could see the first time you tried to connect failed. And the next attempt was a success. I can't remember where I got the firmware from... My attempt:

I read somewhere you must have the device listed here in order to play sound, i need to find this info, but i think is a pulse configuration.

So, i think the problem is the right pulse configuration that must be done to make a link to the hw be available. Still, we need to investigate.

Configuration for mainline:

cat /etc/asound.conf
pcm.!default {
    type plug
    slave {
        pcm "hw:1,0"
    }
}

ctl.!default {
   type hw
   card 1
}

@Bahir Can you try to use this firmware or see the differences? Try the full stack.

https://github.com/RPi-Distro/firmware-nonfree/blob/master/brcm/brcmfmac43430-sdio.txt

Bahir commented 5 years ago

Interesting. I could see the first time you tried to connect failed. And the next attempt was a success. That's because of I forgot to run pulseaudio first time :-)

With this: https://github.com/RPi-Distro/firmware-nonfree/blob/master/brcm/brcmfmac43430-sdio.txt

  1. WIFI stopped to work at all (not associates with AP)
  2. BT the same things
avafinger commented 5 years ago

Did you get all files from https://github.com/RPi-Distro/firmware-nonfree/tree/master/brcm or just the brcmfmac43430-sdio.txt ?

Bahir commented 5 years ago

Yes I've got all of the files. It does not work only if I replace my brcmfmac43430-sdio.txt with the one from there.

avafinger commented 5 years ago

Restore the previous firmware and try this and check any improvement on wlan:

cd /lib/firmware/brcm/
sudo ln -sf brcmfmac43430-sdio.txt "brcmfmac43430-sdio.sinovoip,bananapi zero.txt"
sync
sudo reboot
Bahir commented 5 years ago

That was exactly my configuration (long quotes story I posted today).

My file brcmfmac43430-sdio.txt points to brcmfmac43430-sdio.txt.orig that is the copy of brcmfmac43430-sdio.sinovoip,bananapi zero.txt.

I posted the content of the file brcmfmac43430-sdio.txt and you can check it in the last quote. It is the same as brcmfmac43430-sdio.sinovoip,bananapi zero.txt.

So, what do you suggest is my original configuration and it has no luck.

avafinger commented 5 years ago

Not exactly the same:

[ 6.870887] brcmfmac mmc1:0001:1: Direct firmware load for brcm/brcmfmac43430-sdio.sinovoip,bananapi zero.txt failed with error -2

with the symlink there will be a direct firmware load and can have different behavior than the fallback, that was a hope.

avafinger commented 5 years ago

Just for information, i just repeated the exact same instructions with another board (not bpi-m2z) and i confirm the paplay /usr/share/sounds/alsa/Front_Center.wav is enough to play sound in the CHARGE3. No need for the device to be shown in rfkill list.

Update info TESTED WITH KERNEL 4.4 AND I WILL CHECK WITH 5.3

Anyway, you can install hcidump and run it in the second instance of ssh and monitor the messages during play and try to get a clue where it breaks. You are still ahead of me.

Maybe you can re-install pulse and Bluez and bt tools, and check again until i find out why i can't connect..

Bahir commented 5 years ago

I changed it as you suggested (made symlinks) now dmesg is

But the behavoiur is the same

  1. Strange freezes in network when i activate BT. BTW with 4.20.17 before rampatch were no such freezes but sure they do appear after patchram.
  2. Pulseaudio works bad (dirty sound or it crashes itself) 
    root@bpi-m2z:~# aplay -D pulse /usr/share/sounds/alsa/Front_Center.wav

Also, I tried to install fresh bluez (5.51 from git) and bluez-alsa plugin (https://github.com/Arkq/bluez-alsa) With this plugin we do no need to run pulseaudio. The progress is that with bluez-alsa there no crashes (so there no need to run hcidump) but sound played so dirty as well as with pulseaudio.

Seems like firmware issue or bluez issue.

avafinger commented 5 years ago

FYI, i have the same problem with the other board (that had kernel 4.4 and speaker works with BT) now running kernel 5.3.1. Since both Images (bpi-m2z and the other board) are build from scratch for the kernel 5.3.1 some configuration might be missing (in my case).

avafinger commented 5 years ago

@Bahir Do you have /etc/bluetooth/audio.conf and configured? [General] Enable=Source,Sink,Media,Socket

avafinger commented 5 years ago

Sometimes i see this: Enable=Source,Sink,Media,Socket,Gateway,Control

avafinger commented 5 years ago

@Bahir After some configurations and installations..... I get the sound coming out from the BT speaker now, playing Front_Center is almost clear but in slow motion, something like Froooooonnnnt Ceeeeeenter.

Pulse is still running after several play commands: paplay /usr/share/sounds/alsa/Front_Center.wav and aplay -D pulse /usr/share/sounds/alsa/Front_Center.wav

The CHARGE3 battery is very low, could be this.... Just turned off now. So there is hope...

@Bahir After some configurations and installations..... I get the sound coming out from the BT speaker now, playing Front_Center is almost clear but in slow motion, something like Froooooonnnnt Ceeeeeenter.

Mine is the same effect but with some distortion (like Matrix sound). As for me it not depends on battery level. What about my /etc/bluetooth/audio.conf. It is. This section contains general options [General] Enable=Source,Sink,Media,Socket

avafinger commented 5 years ago

Also, I noticed that when I activate something with BT (pulseaduio, bluetoothctl) the WIFI connection sometimes interrupts responding (strange delays when i type in ssh console). And sometimes I need to restart ssh session at all after I activated BT.

Ok, i am now testing with wlan0. BT plays most of the time but sometimes very laggy. There must be a way to parametrize this or change this delay.

To fix the ssh issue you have, edit the fie /etc/network/interfaces and uncomment the two lines:

wireless-mode Managed

wireless-power off

If there isn't a way to change this lag (BT) i will try to create Ubuntu EON Image if that is possible with armhf. No time frame for this.

avafinger commented 5 years ago

Small update. I just tried to play some mp3 and the sound is really bad, maybe similar to what you described.

I used sox sudo apt-get install sox libsox-fmt-all:

play music.mp3

I played this: https://www.soundhelix.com/examples/mp3/SoundHelix-Song-1.mp3

avafinger commented 5 years ago

Today I pushed an 8GB Image here: https://github.com/avafinger/bananapi-zero-ubuntu-base-minimal/releases/tag/v2.4

You still need to install ALSA, Bluetooth and then test the latest Bluez stack. So we can see if it has been fixed with the latest and cutting edge.

The Image is a bare minimum Image that can suit every need, Desktop side or Server side

avafinger commented 5 years ago

Install BT stack:

sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install dialog alsa-utils libasound2 alsa-base
sudo apt-get install bluez bluez-tools libbluetooth-dev
sudo apt-get install pulseaudio pulseaudio-utils pavucontrol pulseaudio-module-bluetooth

then start configuring...

avafinger commented 5 years ago

Update. Playing aplay -D pulse /usr/share/sounds/alsa/Front_Center.wav is now fixed in Ubuntu 19.10 but playing mp3 audio no. I think must be a way to configure a2dp but did not find a way.... :(

I just tried to play the MP3 file on another board and i got the exact same results as bpi-m2z. I can play Wav sound just fine with: sudo paplay /usr/share/sounds/alsa/Front_Left.wav

But... Playing the mp3 (the one i linked) is just noise..

So, i will put it this way... BT is broken on 5.x regarding sound OR we need a codec (the right codec) to play that mp3.

Maybe someone with BT experience read this and share the right way to configure this.

I have: Active Profile: a2dp_sink and you Active Profile: headset_head_unit

Any specific reason?

I have no idea. Now it is SINK

I've noticed that pactl list card shows sink as active profile until aplay or paplay crashed. After that it is Active Profile: headset_head_unit.

And, now I suddenly started to get these errors (without touching any configs and no new packages installed, just played with bluetoothctl connecting headset and played sounds).

Oct 12 15:28:13 bpi-m2z pulseaudio[633]: E: [pulseaudio] bluez5-util.c: GetManagedObjects() failed: org.freedesktop.DBus.Error.AccessDenied: Rejected send message, 2 matched rules; type="method_call", sender=":1.45" (uid=1000 pid=633 comm="/usr/bin/pulseaudio --daemonize=no ") interface="org.freedesktop.DBus.ObjectManager" member="GetManagedObjects" error name="(unset)" requested_reply="0" destination="org.bluez" (uid=0 pid=381 comm="/usr/lib/bluetooth/bluetoothd ")

Reboot did not help. The error is still here.

avafinger commented 5 years ago

I think Bluetooth (armhf) is buggy. In Arm64 BT works pretty good and stable. Unfortunately, my fix did not survive a reboot and now the same error i mentioned above forces a disconnect from pulseaudio.

You could try:

pusleaudio -k
pusleaudio --start
pactl set-card-profile 2 a2dp_sink
avafinger commented 5 years ago

and check for some error:

sudo cat /var/log/syslog | grep -i blue
sudo cat /var/log/syslog | grep -i err
sudo cat /var/log/syslog | grep -i fail
Bahir commented 5 years ago

A bit of progress. I connected antenna to bpi and now bluetooth does not crash while playing sound, like aplay: pcm_write:2053: write error: Input/output error. One problem found and gone. But the sound is still barking while playing. Seems like something wrong with baudrate and a channel speed is not enough to pass WAV or it drops packets (I'm not sure, just a guess)

meisterbasti commented 4 years ago

Hey, with the new Kernel 5.3.18 I was able to pair and connect to a bluetooth speaker. But when I try to play a .wav file the sound is very choppy

Why is it that choppy ? I wan't to detect objects with an attached Coral Edge TPU from Google and what to hear the result over the speaker.

The same problem with a connected Bluetooth Headphones...

I also tried out with connected monitor on the banana pi with disabling wlan0. But still the same. The sound is always very choppy

At the beginning it seems to fix the problem. Sound started with good quality but after maybe 1 sec the sound is interrupted completely and the device lost the connection to the banana pi. Bluetoothctl is no longer connected.

Looks like BT speed is still wrong. I have seen 921600 and 1500000 max speed for this device. Currently set to 1500000, maybe it should be 921600.

You could try different speed values.

PS: make a backup file
