Title: Alsa sound not working after d-u
Post by: effo on 2018/12/01, 12:16:04: Two weeks ago I did a huge d-u. No errors, all worked fine. But I can not get any sound in alsa anymore. Sound works fine in KDE.

Code: [Select]
/home/effo> speaker-test speaker-test 1.1.7 Playback device is default Stream parameters are 48000Hz, S16_LE, 1 channels Using 16 octaves of pink noise ALSA lib pcm_dmix.c:1099:(snd_pcm_dmix_open) unable to open slave Playback open error: -2,No such file or directory
This part look suspicious:
Playback open error: -2,No such file or directory

Code: [Select]

Any ideas on how to fix this?

Post by: finotti on 2018/12/01, 14:52:18: Did you check levels in alsamixer?
Title: Re: Alsa sound not working after d-u
Post by: effo on 2018/12/02, 13:42:45: Yes, levels in mixer are ok.

This is something else here that not is ok. When I try to start mocp I see these errors:

Code: [Select]
home/effo> mocp Running the server... Trying JACK... Trying ALSA... Trying OSS... FATAL_ERROR: No valid sound driver! FATAL_ERROR: Server exited!
If I open qmmp and try to play a track, I see this:

Code: [Select]

Post by: dibl on 2018/12/02, 15:20:34: I lost audio on one of my laptops, an LXQt desktop, about 3 weeks ago now. Troubleshooting did not find any problem, but sound was gone.

I finally reinstalled all the alsa-related packages, out of X, and then rebooted and it was fixed.

Post by: piper on 2018/12/02, 15:37:11: This is a long shot (considering this happened November 03)

You can try and backup

Code: [Select]
/etc/alsa/conf.d
to a different folder/partition/whatever

Then

Code: [Select]
mv /etc/alsa/conf.d{,_bak}
login/reboot

Probably won't work, but worth a try
Title: Re: Alsa sound not working after d-u
Post by: effo on 2018/12/02, 20:32:58: Unfortunately you are right piper, it did't help.

I purged alsa-utils and gstreamer1.0-plugins and re-install with no luck. There are libasound2-stuff too, but if I try to purge anything there, there is a lot to be removed.

Are there other packages to re-install...?

Code: [Select]
root@siductionbox:~# dpkg -l | grep -i alsa ii alsa-utils 1.1.7-1 amd64 Utilities for configuring and using ALSA ii gstreamer1.0-alsa:amd64 1.14.4-1 amd64 GStreamer plugin for ALSA ii libasound2:amd64 1.1.7-1+b1 amd64 shared library for ALSA applications ii libasound2:i386 1.1.7-1+b1 i386 shared library for ALSA applications ii libasound2-data 1.1.7-1 all Configuration files and profiles for ALSA drivers ii libasound2-plugins:amd64 1.1.7-3 amd64 ALSA library additional plugins ii libasound2-plugins:i386 1.1.7-3 i386 ALSA library additional plugins

Post by: dibl on 2018/12/02, 22:11:35: On a working system (amd64 only) my alsa packages are exactly the same as yours except I don't have the i386 versions.

What does

Code: [Select]
inxi -A
show?

You say sound works fine in KDE -- do you mean in the systemsettings > hardware > multimedia > Audio and Video setting?
Title: Re: Alsa sound not working after d-u

I have sound in Chromium and VLC, but no sound in qmmp and mocp
Title: Re: Alsa sound not working after d-u
Post by: dibl on 2018/12/02, 22:44:59: If the sound test in KDE's systemsettings > hardware > multimedia > Audio and Video setting works (verify that the correct sound playback device for the Music category is at the top of the list), and also since VLC and the browser play sound, it is beginning to sound like bugs in qmmp and mocp, which I do not use and don't know anything about.

Post by: der_bud on 2018/12/03, 00:06:56: There is a moc bug report with similar symptoms: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=913277
Title: Re: Alsa sound not working after d-u
Post by: piper on 2018/12/03, 00:47:33: Last resort

Code: [Select]
killall -9 pulseaudio apt purge pulseaudio apt clean; apt autoremove
reboot.

Code: [Select]
rm -r ~/.pulse ~/.asound* ~/.pulse-cookie ~/.config/pulse apt install pulseaudio alsa force-reload
Title: Re: Alsa sound not working after d-u
Post by: effo on 2018/12/03, 20:57:01: I did read the bug report on moc and it looks like the same problem. But my guess is that this is not moc related, more an ALSA thing as I have problem with speaker-test:

Code: [Select]
/home/effo> speaker-test speaker-test 1.1.7 Playback device is default Stream parameters are 48000Hz, S16_LE, 1 channels Using 16 octaves of pink noise ALSA lib pcm_dmix.c:1099:(snd_pcm_dmix_open) unable to open slave Playback open error: -2,No such file or directory /home/effo/.config/pulse>
Hmm, "unable to open slave", are we trying to use the wrong device or something like that...?
Let's look at all cards:

Code: [Select]
/home/effo> aplay -L null Discard all samples (playback) or generate zero samples (capture) hdmi:CARD=HDMI,DEV=0 HDA ATI HDMI, HDMI 0 HDMI Audio Output dmix:CARD=HDMI,DEV=3 HDA ATI HDMI, HDMI 0 Direct sample mixing device dsnoop:CARD=HDMI,DEV=3 HDA ATI HDMI, HDMI 0 Direct sample snooping device hw:CARD=HDMI,DEV=3 HDA ATI HDMI, HDMI 0 Direct hardware device without any conversions plughw:CARD=HDMI,DEV=3 HDA ATI HDMI, HDMI 0 Hardware device with all software conversions default:CARD=Generic HD-Audio Generic, ALC887-VD Analog Default Audio Device sysdefault:CARD=Generic HD-Audio Generic, ALC887-VD Analog Default Audio Device front:CARD=Generic,DEV=0 HD-Audio Generic, ALC887-VD Analog Front speakers surround21:CARD=Generic,DEV=0 HD-Audio Generic, ALC887-VD Analog 2.1 Surround output to Front and Subwoofer speakers surround40:CARD=Generic,DEV=0 HD-Audio Generic, ALC887-VD Analog 4.0 Surround output to Front and Rear speakers surround41:CARD=Generic,DEV=0 HD-Audio Generic, ALC887-VD Analog 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=Generic,DEV=0 HD-Audio Generic, ALC887-VD Analog 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=Generic,DEV=0 HD-Audio Generic, ALC887-VD Analog 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=Generic,DEV=0 HD-Audio Generic, ALC887-VD Analog 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers dmix:CARD=Generic,DEV=0 HD-Audio Generic, ALC887-VD Analog Direct sample mixing device dsnoop:CARD=Generic,DEV=0 HD-Audio Generic, ALC887-VD Analog Direct sample snooping device hw:CARD=Generic,DEV=0 HD-Audio Generic, ALC887-VD Analog Direct hardware device without any conversions plughw:CARD=Generic,DEV=0 HD-Audio Generic, ALC887-VD Analog Hardware device with all software conversions
Ok, I want to use default:CARD=Generic
I'll try it with speaker-test:

Code: [Select]
/home/effo> speaker-test -Ddefault:Generic speaker-test 1.1.7 Playback device is default:Generic Stream parameters are 48000Hz, S16_LE, 1 channels Using 16 octaves of pink noise Rate set to 48000Hz (requested 48000Hz) Buffer size range from 2048 to 16384 Period size range from 1024 to 1024 Using max buffer size 16384 Periods = 4 was set period_size = 1024 was set buffer_size = 16384 0 - Front Left Time per period = 2,654912 0 - Front Left Time per period = 2,986484
YES - sound!

I can even play music with aplay:
Code: [Select]
/home/effo> aplay --device default:CARD=Generic Muse_-_Please,_Please,_Please,_Let_Me_Get_What_I_Want.wav Playing WAVE 'Muse_-_Please,_Please,_Please,_Let_Me_Get_What_I_Want.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
So I guess that alsa uses the wrong device as the default one. But why? And how to change that?

Did some googling and found https://www.alsa-project.org/main/index.php/Setting_the_default_device
So listed my cards:

Code: [Select]
/home/effo> cat /proc/asound/cards 0 [HDMI ]: HDA-Intel - HDA ATI HDMI HDA ATI HDMI at 0xfeb44000 irq 42 1 [Generic ]: HDA-Intel - HD-Audio Generic HD-Audio Generic at 0xfeb40000 irq 16
Then created /etc/asound.conf and added
Code: [Select]
defaults.pcm.card 1 defaults.ctl.card 1
And now mocp and qmmp works!

But I don't like adding random config-files, this feels like a cludge :(

Shall I report my findings somewhere?

Post by: dibl on 2018/12/03, 21:19:45: Using KDE/Plasma, it has been a long time since I had much trouble with audio. With phonon, phonon-backend-gstreamer, and pulseaudio installed along with the list of alsa packages shown above, you use systemsettings > hardware > multimedia > Audio and Video, choose "Music" under Audio Playback, then under the "Backend" tab you make sure phonon-gstreamer is selected, and under the "Device Preference" tab you use the "Test" button to see which works, and use the up-down adjustment to put the desired device on top of the list.
