[Solved] pulseaudio/alsa

rassawyer · 2015-10-05 05:49:24

Hello. I am running Arch (4.2.1-1-ARCH) on a mid 2010 macbook. When I first got it setup, everything worked great, but then somewhere along the way, my audio stopped cooperating. I don't even remeber now what the original issue was (I was away from my laptop for almost 6 months, not by choice). Anyway, the current situation is this. Pulseaudio kept defaulting to the wrong audio card, which I don't even know how is possible, since I only have one card. When I booted, it would come up and work fine for 30 seconds to a minute, then it would switch cards, and I would get an error related to PCM whenever I tried anything like pulseaudio-ctl up, etc. I tried all manner of troubleshooting and suggestions from numerous wiki pages and forum pages, but had no success. My last attempt was to backup all the files related to ALSA and pulseaudio and remove them and reinstall. Great idea... Except that I backed them up by renaming them to .bak, and then when I deleted all the *pulse* files, it took out my backups as well. I got pulseaudio, ALSA, ALSA-plugins, ALSA-utils, etc all reinstalled, but now I get errors about missing .so files.specifically,

/usr/lib/chromium/chromium: error while loading shared libraries: libpulsecommon-7.0.so: cannot open shared object file: No such file or directory

Can anyone point me in the right direction to reconfigure this mess, or should I reinstall Arch? (I installed Arch to its own partition, so I can fairly easily reinstall it without losing personal files, etc.) Any logs, etc that will help, just ask. Thanks in advance!!

update. I got the missing .so(s) reinstalled, and I'm back to where I started. I have sound, but I still keep getting the PCM error, e.g.

[rassawyer@truegeekllc pulseaudio-ctl]$ amixer set PCM unmute
amixer: Unable to find simple control 'PCM',0

[rassawyer@truegeekllc pulseaudio-ctl]$ amixer set master unmute
amixer: Unable to find simple control 'master',0

update #2. If I kill pulseaudio

pulseaudio -k

the sound card goes back to the proper assignment, and everything works great until pulseaudio respawns...

This does not help you, but the update to PulseAudio 7 does seem like a huge pile. On one of my PCs everything seems ok (thankfully) but on my media center every time the PC rebooted everything was muted by default. I tried different settings in /etc/pulse/daemon.conf and tried deleting ~/.config/pulse for all users but nothing made it work right...

In the end, I binned Pulse and just used Alsa as it only runs one app (Kodi) anyway....

Does downgrading to Pulseaudio 6 help? I mean I cant be bothered to look into it myself as I am happy enough using Alsa (in movies the sound of the people speaking seem closer to the background stuff too, so I don't have to change volume so much between talking and action scenes), but I do think Pulse 7 is probably your issue too. It seems totally pants.

To prevent pulse from spawning, as your user execute

systemctl --user mask pulseaudio.socket

In general you should provide some more info, namely the output of

aplay -l
pacmd list-sinks
pacmd list-cards
sudo fuser -v /dev/snd/*

and tell us which of those cards you want as default, you already went into e.g. pavucontrol and set your wanted card as default I hope? If you haven't go do so.

And what exactly did you try from the wiki, we don't have magic glassballs here

pulseaudio --start

gives

Honestly I've tried so many different wiki pages that I lost track. I do know that I tried editing the default.pa file, I remove the asound.state file, I removed all the userspace .config files related to both pulse and ALSA, etc. I should have clarified, I'm certain if saying that it is trying to use the wrong card is really accurate. If I get pulseaudio to start, and open alsamixer, then hit F6 to select the sound card, I have - (default), which is what it is on, and the alsamixer panel has only one adjustment slider. If I select 0 HDA NVidia, which is what it used to use, and what I want it to use, I can adjust master, headphones, speakers, bass level, PCM etc all independently. I haven't figured out how to attach images, or I would have screenshots for some of this.

Screenshots are on my website:

Edit: attempting to downgrade to previous pulseaudio gives this

Pulseaudio exposing only one mixer on ALSA's side is normal and expected behaviour, pulseaudio takes over the soundcard, if you intend to use it you should do most of the configuration via pulseaudio's tools. This is no indication of pulse using the wrong card.

What we now have to find out is why pulseaudio isn't starting occasionally which is what you want to fix and wherein your real problem lies. Assuming you haven't done the systemctl mask yet what is the output of

journalctl -u=pulseaudio.service
sudo fuser -v /dev/snd/* #You forgot that one and it happens to be one of the most important ones
pulseaudio -vvv #If you have done the mask already you should be able to start it manually like this and get some more verbose output

Contents of /etc/asound.conf and if you edited the /etc/pulse/default.pa post that as well to be sure

For completeness sake also post

pacman -Qs pulseaudio
pacman -Qs alsa-plugin

Leave the downgrading to the side for now, I don't think this is really the underlying issue here.

I see I forgot to say this earlier, thank you very much for your assistance!! I hate to be the newb needing help, but I'm very glad for folks like you who are willing to help!

rassawyer · 2015-10-06 00:19:52

Addendum: Pulseaudio was running when I ran those commands. If you want to see what it gives with pulseaudio stopped, let me know. Meanwhile, since it is running, I'll run the pacmd commands and post what they return.

Two things, you lack libpulse (however you managed to do that, it's a hard dep of many packages...) and in your default.pa one of the module-alsa loads is uncommented (line 46) comment that again. If, with these adjustments in place, it happens again that pulseaudio doesn't start/is killed, repost the output of

sudo fuser -v /dev/snd/*
pulseaudio -vvv

Mask and unmask the pulseaudio.socket as necessary (don't mask the socket if you intend to use pulseaudio normally, mask it if it crashes to get debug output from pulseaudio -vvv)

PS: Please refrain from quadruple posting, there's an edit button under each post, use it to prepend additional information to your original post

I apologize for the quadruple post.

installin libpulse gives the following

pulseaudio is running, starting, and auto-spawning flawlessly now. I do however still have the "No simple control 'PCM' error".

Sound works, keyboard controls work. Thank you much for your assitence!!

As said, this is normal. if you actually want to change your amixer PCM you have to invoke it with the device you are going to use e.g.

amixer -c0 set PCM unmute

however if you use pulseaudio you should use its tools to do that e.g. pavucontrol or

pacmd set-sink-volume

or pulseaudio-ctl (don't use it myself but it surely provides you with similar capabilities) they are going to be a more reliable way of handling your sound with pulseaudio.

However good to see that it is solved now, don't forget to prepend [SOLVED] to the title of your inital post by editing it.
