alsa audio #30

Closed lbernstone closed 4 years ago

lbernstone commented 4 years ago

As you know, I am trying to get RetroPie working on this device. I am unable to get alsa sound on the HDMI output working with the Ubuntu 19.10 image. No errors, but no sound. I have disabled pulseaudio by unlinking the service and removing /etc/alsa/conf.d. I have tried using both hw devices in speaker-test, but no sounds. My alsa layout looks like this:

I do get some issues with the codec device in dmesg:

avafinger commented 4 years ago

Firstly you should not remove the link! And pulseaudio should be enabled, not a requirement but better so.

Steps to get Audio (HDMI output)

special attention to "Play audio to HDMI" section here: https://github.com/avafinger/bananapi-zero-ubuntu-base-minimal/issues/27#issuecomment-538648533

lbernstone commented 4 years ago

Didn't see that issue, as my bluetooth is working :smile:. I'll reset and give it a shot.

This is not HDMI, and it was finally mapped at the end, just ignore it.

Good, save this configuration for later reference! Maybe you found how it should be configured!

lbernstone commented 4 years ago

It seems like it is all working, just no sound output. I can see the device and alsamixer takes me directly to the allwinner,hdmi hw device. There's no errors about an interrupted stream or timeout. I did have to add the ubuntu user to the audio group along with the asound.conf, but then everything looks like you show in that thread. There are no options in the mixer for the hw:allwinner,hdmi device, so I can't "enable all output" there.

lbernstone commented 4 years ago

I just tested with bluetooth. I am able to pair a speaker, it automatically switches to that sink, plays the audio, but it stutters a lot.

lbernstone commented 4 years ago

Any ideas how to troubleshoot this? Do you get sound with the U19.10 image?

avafinger commented 4 years ago

BT? I got it working without "stuttering". It did not survive a reboot, the same procedure on the next boot disconnect the BT every time i try.

Hdmi-sound works on Ubuntu 19.10. To enable hdmi sound you need to configure asound.conf

pcm.!default {
    type plug
    slave {
        pcm "hw:1,0"
    }
}

ctl.!default {
   type hw
   card 1
}

Test with: sudo aplay -D sysdefault:CARD=1 /usr/share/sounds/alsa/Front_Left.wav

lbernstone commented 4 years ago

No sound. No errors. I don't think this tv has anything weird going on with it. Other devices work out of the box. The old jesse/armbian image gives me sound (but the dtb is compiled into the kernel, so I can't compare).

Do you have a spare sd card and a linux box?

avafinger commented 4 years ago

I can make an Image 8GB with my setup... No linux Box needed.

lbernstone commented 4 years ago

Sure. I have lots of stuff kicking around :) I should have a couple extra devices coming in the mail this afternoon as well.

avafinger commented 4 years ago

I will update kernel and prepare an 8GB Image and you give it a try, it takes some time to prepare one here...

Still no sound.

lbernstone commented 4 years ago

I am now seeing this in the dmesg log. Not sure if it is involved with the hdmi sound, but it an i2s error seems like it could be related:

avafinger commented 4 years ago

I don't get any errors while playing music.

Here is the tip, use the Armbian Kernel that you say hdmi-sound works:

Good luck.
