Bugfix in AsyncAudioDeviceAlsa/AsyncAudioIO doesnt work on raspberry pi 2 #312

Closed dl1esk closed 6 years ago

dl1esk commented 7 years ago

This Bugfix makes trouble on Raspberry Pi2 after update no sound and Repeater is still up then

Axel-DG1BBQ commented 7 years ago

I have the same problem. When starting SvxLink on the Raspberry Pi3b will key up the TX, but will not key down again.

Axel-DG1BBQ commented 7 years ago

Here's a quick fix for the Raspberry3b (should work elsewhere too) At leatst on my sytems the working libraries libasyncaudio.so.1.4.0.99.2 libasynccore.so.1.4.0.99.2 libasynccpp .so.1.4.0.99.2 were not deleted.

go to /usr/lib/arm-linux-gnuabihf: edit the link libasyncaudio.so.1.4 to point to libasyncaudio.so.1.4.0.99.2 edit the link libasynccore.so.1.4 to point to libasynccore.so.1.4.0.99.2 edit the link libasynccpp.so.1.4 to point to libasyncaudio.so.1.4.0.99.2

delete the faulty libraries: libasyncaudio.so.1.4.0.99.3 libasynccore.so.1.4.0.99.3 libasyncaudio.so.1.4.0.99.3

Shoud work right away. if not, just restart svxlink.

I have updated my svxlink with latest sources and all working OK and I have the following version of libraries: wrz 22 10:45 libasyncaudio.so.1.4 -> libasyncaudio.so.1.4.99.4-svxreflector wrz 22 10:25 libasyncaudio.so.1.4.99.4-svxreflector wrz 22 10:45 libasynccore.so.1.4 -> libasynccore.so.1.4.99.4-svxreflector wrz 22 10:23 libasynccore.so.1.4.99.4-svxreflector wrz 22 10:45 libasynccpp.so.1.4 -> libasynccpp.so.1.4.99.4-svxreflector wrz 22 10:23 libasynccpp.so.1.4.99.4-svxreflector

Hi Walek,

where do u get that Libary number.....?! latest sources have:

2 src/versions @@ -5,7 +5,7 @@ QTEL=1.2.2.99.1 LIBECHOLIB=1.3.2.99.0

Version for the Async library

-LIBASYNC=1.4.0.99.2 +LIBASYNC=1.4.0.99.3 !!

SvxLink versions

SVXLINK=1.5.99.9

and they don`t work on the Raspberry Pi 2/3

sp2ong commented 7 years ago

Hi,

I forgot to add that I have use svxlink with support svxreflector links (svxLink v1.5.99.12-svxreflector). I have the similar problem on "RPI Zero W" after update to the new version svxlink but I have removed all libraries svxlink from /usr/lib/... and again run make install all works. My way to compile svxlink with support svxreflector links in following:

git clone https://github.com/sm0svx/svxlink.git cd svxlink git pull cd src/svxlink git checkout svxreflector cd ../ mkdir build cd build cmake -DUSE_QT=OFF -DCMAKE_INSTALL_PREFIX=/usr -DSYSCONF_INSTALL_DIR=/etc -DLOCAL_STATE_DIR=/var -DCMAKE_BUILD_TYPE=Release .. make (before make install I have remove all old libraries svxlink) make install ldconfig

dl1esk commented 7 years ago

the old libaries are not the problem because the new libaries will be copied over there and correctly linked. but that versions doesn`t work. if u change the link to the old libaries everything is fine

sp2ong commented 7 years ago

Ok But with my hardware "Raspberry Pi Zero W" with last update svxlink all working. I have used on "RPI Zero W" latest version Raspbian: Stretch It may be it is problem with RPI 2/3

Hi

I confirm the problem with latest update svxlink sources. I have the update on other my echolink computer with HP T5735 and when I have start svxlink PTT is On and never OFF without any sounds. When I have switched back to the previous version libasyncaudio v1.4.99.3-svxreflector instead v1.4.99.4-svxreflector all working OK

73 Waldek

sp2ong commented 7 years ago

I have yet another problem with the latest svxlink update. When I use alsa equalizer for [Tx1] and when the first time PTT is turned on is no audio and PTT does not turn off. I must manually stop svxlink. The svxlink without update works correctly with alsa equalizer.

n7ipb commented 7 years ago

I'll also confirm this.
Fresh RPi raspian install with v1.5.99.12-svxreflector. Once keyed the repeater never unkeys and the log shows squelch not closing. Even running devcal -r alone without ever having started svxlink fails.

sm0svx commented 7 years ago

That's unfortunate. It works fine here on my Cubieboard and my laptop. I'll try to fire up my Pi2 to see if I can reproduce the problem.

A tip; when running software directly from a version controlled repository, learn a couple of commands to revert back to the previous version in case of trouble. Mixing old libs with newer software (by removing the new libs) is not to be recommended even it worked in this case. What you should do is something like this:

sp2ong commented 7 years ago

Hi Tobias,

Thank you for advice I have tried using git checkout ORGI_HEAD from master but without success:

cd svxlink/ git checkout master Already on 'master' Your branch is up-to-date with 'origin/master'. git checkout ORIG_HEAD error: pathspec 'ORIG_HEAD' did not match any file(s) known to git.

sp2ong commented 7 years ago

I have use svxreflector branch and I would like to have stayed with sources from GIT on SHA 7f2a063153538bb064f75c15eb70495ef8f29c96 from Commits on Jul 28, 2017

sm0svx commented 7 years ago

Strange that ORIG_HEAD did not work. You can just do

git checkout 7f2a063153538bb064f75c15eb70495ef8f29c96

to get a specific revision.

sm0svx commented 7 years ago

After many hours I finally got SvxLink running on the RPi2. I had problems getting audio input to work until I remembered that the RPi have problems with delivering enough current on the USB bus for some devices. Everything started working when I connected a USB hub.

Unfortunately everything seem to work on my Rpi. No hanging squelches or tx:es.

Can someone post a rx config that produce the error on their system? Especially interesting that @n7ipb got the problem with devcal. Maybe you can post your rx config?

sp2ong commented 7 years ago

Hi Tobias,

I have the problem with HP Terminal T5735 with latest update svxlink , my Rx1 config: [Rx1] TYPE=Local AUDIO_DEV=alsa:plughw:1 AUDIO_CHANNEL=0 SQL_DET=SIGLEV SQL_START_DELAY=1000 SQL_DELAY=50 SQL_HANGTIME=150 SQL_TAIL_ELIM=200 SIGLEV_DET=NOISE SIGLEV_SLOPE=-54.82 SIGLEV_OFFSET=364.87 SIGLEV_OPEN_THRESH=25 SIGLEV_CLOSE_THRESH=10 DEEMPHASIS=0 PEAK_METER=0 DTMF_DEC_TYPE=INTERNAL DTMF_MUTING=1 DTMF_HANGTIME=40

But all we have problem with Tx1 because after start Tx1 PTT ON and never OFF and no audio My Tx1:

[Tx1] TYPE=Local

AUDIO_DEV=alsa:plughw:1

AUDIO_DEV=alsa:equal AUDIO_CHANNEL=0 PTT_TYPE=SerialPin PTT_PORT=/dev/ttyS0 PTT_PIN=RTS PTT_HANGTIME=500 TIMEOUT=1800 TX_DELAY=500 PREEMPHASIS=0 DTMF_TONE_LENGTH=100 DTMF_TONE_SPACING=50 DTMF_DIGIT_PWR=-18

I have use for Tx1 pass audio via alsamixer equalizer which work with svxlink before last update I have Debian Jessie

sm0svx commented 7 years ago

Yes, TX config is good to have as well. Thanks!

Do you mean that the TX goes on without the squelch ever being open? I thought the TX hang because the squelch never closes?

sp2ong commented 7 years ago

Hi, This problem appears for example I have to start svxlink and when first time TX ON never TX OFF and never transmit any audio. The TX ON start for example when audio incoming from svxreflector link or after start svxlink and I have PTT ON in my radio and svxlink typical send roger beep to confirm received signal but svxlink TX ON and not send roger beep and never OFF, I must manual stop svxlink

sp2ong commented 7 years ago

I think we need more feedback from others who try use latest updates

sm0svx commented 7 years ago

Ok. Sounds like we should focus on the TX.

n7ipb commented 7 years ago

I just did a fresh install with the minimum necessary to build and run svxlink.

New SD card, 2017-09-07-raspbian-stretch.img

I installed the usual support then checked out the latest svxlink. git clone https://github.com/sm0svx/svxlink.git and checked out svxreflector

Configured with: cmake -DCMAKE_INSTALL_PREFIX=/usr -DSYSCONF_INSTALL_DIR=/etc -DLOCAL_STATE_DIR=/var -DUSE_OSS=NO -DUSE_QT=NO -DWITH_SYSTEMD=YES ..

Then build and install.

The attached gpio and svxlink config files were installed and I ran devcal after first doing svxlink_gpio_up

For the receiver: ./devcal /etc/svxlink/svxlink.conf -r RxRepeater The normal messages were output but not the line that normally shows the deviation and it takes a ctrl-c to get back a prompt.

Then for TX: ./devcal /etc/svxlink/svxlink.conf -t TxRepeater The normal header shows then when you press 'T' the transmitter comes on but it doesn't go off when you press 'T' again and there is no audio transmitted. The only way out is to do a ctrl-c.

To make it even more confusing, if I start svxlink everything works.

Oct 01 2017 22:32:37.242: RxRepeater: The squelch is OPEN (82.3206) Oct 01 2017 22:32:37.874: RxRepeater: The squelch is CLOSED (3.05542) Oct 01 2017 22:32:43.669: TxRepeater: Turning the transmitter OFF

Yesterday it wasn't working with a more complex setup so I'll go back to that and see if there are any additional clues.

n7ipb commented 7 years ago

Ok, I went back to using the svxlink.conf file that wasn't working yesterday, and indeed it also fails to run today. The squelch opens, the repeater transmits...and hangs until I stop svxlink.

I was able to narrow it down to one part of the configuration.

On all my systems I have darkice running to stream the audio so I have an alsa loopback device loaded with 'sudo modprobe snd_aloop'

I have the attached asound.conf file in /etc

Add the mtx.txt file to the end of the svxlink.conf from my previous message and change the RepeaterLogic TX to RepeaterMultiTx

When RepeaterMultiTx contains TxStream svxlink will lock up. Remove it and it works fine.

Prior to the latest Async changes this worked fine.

dl1esk commented 6 years ago

I also have a loopback Device in my RX Config, i use it once a week to send Amateur Radio News.. My Rx Section:

[Rx1] TYPE=Local AUDIO_DEV=alsa:hw:1 GPIO_SQL_PIN=gpio3

[Tx1] TYPE=Local AUDIO_DEV=alsa:plug:plugequal AUDIO_FILTER=BpBu4/50-4000 PTT_PIN=gpio17 PTT_TYPE=GPIO GPIO_PTT_PIN=gpio17

I have the same that no Audio then and when Squelch opens once it stays open and TX doesnt switch off anymore.

I will do a Test agn today without the Equalizer. But for good Audio i need that Equalizer...

dl1esk commented 6 years ago

i narrowed down the problem.... if u use AUDIO_DEV=alsa:plug:plugequal in ur TX to make the Audio Quality better the problem occurs if u open the repeater the squelch will be open and doesnt close and tx will be on all the time if u use svxlink without equalizer everything is fine Tobias do u have an idea whats going wrong there ?!

sp2ong commented 6 years ago

Hi Tobias

I have to try to find how to get version sources from git for branch svxreflector before update AysnAudio

When I have run following

git checkout svxreflector

I switch to svxreflector but now I would like to have in branch svxreflector source with SHA 7f2a063153538bb064f75c15eb70495ef8f29c96

and run

git checkout 7f2a063153538bb064f75c15eb70495ef8f29c96

it is OK but sources are before the last update but I don't have svxreflector source in svxlink sources tree

I have solved problem with manually revert sources for AudioSyncxxxx files

sm0svx commented 6 years ago

Thanks for the detailed reports! Sorry I haven't been able to deal with the problem until now. I'll try to set up a config with a loopback device to see if I can trigger the problem.

@sp2ong, hmmm, yes... I guess it's not that simple. Try "git log --first-parent svxreflector". You probably want commit f071bca6b6c2de6ad3f31f9db84de969913f80a6.

sm0svx commented 6 years ago

I managed to reproduce the problem on my laptop using the config that @n7ipb provided. Now I just have to find the bug...

sm0svx commented 6 years ago

Bug fixed in latest master and svxreflector branches. Please tell me if it's working now in your setup.

sp2ong commented 6 years ago

Hi Tobias,

I have to get the fresh code from github and switch to svxreflector and replace on all my local nodes to the new version and reload new svxreflector. All node where I have used alsa loop and alsa equalizer now working without audio problems. Thank you for fix problem. 73 Waldek

n7ipb commented 6 years ago

The latest code seems to have fixed the bug introduced by the AsyncAudioIO bug fixes. I no longer see the problem with PTT.

Unfortunately I had hoped that issue #209 would be solved by the AsyncAudioIO changes but I'm still seeing the assertion when using CTCSS.

sm0svx commented 6 years ago

That problem is probably not connected directly to any audio I/O issue but rather have something to do with code closer to the squelch/CTCSS handling.

This issue seem to be solved though so I'm closing it.
