[solved] no sound with multimedia apps using Pulseaudio Dummy drive

kozaki · 2014-09-01 17:19:55

It seems audio issues are kindof frequent atm, but I couldn't solve the strange issue using the informations provided in the threads nor the wiki

Issue:
One app plays audio just fine: Deadbeef Audio player, but no activity shows up in Pavucontrol while playing.
Deadbeef uses default Alsa outpput (currently Pulse audio server)

The other multimedia that I use or tried (mplayer, VLC and paplay test.wav) play files with no sound to be heard. Pavucontrol just shows 'dummy output' activity
as for mplayer that is the case with default pulse and alsa audio drivers

Context:
1/ Recently switched from ALSA to PulseAudio
Have no ~/.asoundrc

2/ First appeared when:
Installed software updates last week. I lazily hoped it will resolve itself with the next update which it didn't so far. None of the packets I updated had linux|pulse|alsa|sound|audio in its name.
Another issue appeared at the same time: no software is able to play any media from the DVD drive. The optical drive itself is well recognized whether by 'lsscsi' or /proc/sys/dev/cdrom/info

3/ PulseAudio did not start today after booting the system
$ pulseaudio --start
E: [pulseaudio] main.c: daemon startup failed
Started OK after commenting "/etc/pulse/default.pa" config line that remap microphone to mono for Skype (as per the Pulseaudio wiki)

I guess it might be a rather basic configuration step that I missed and am blind to see. If so, sorry for wasting your time :-/ Hint appreciated.

Read how to post correctly to get English output.

Really? What do you think relevant_snd_module is? When you copy something from another thread, maybe it would be wise to read through it first. I tried to explain that there is no relevant_snd_module, it is a hint to the user, yes you, to use the module that is relevant in users case, which often is snd_hda_intel, which again is also mentioned in the other thread. Read it and correct your post accordingly please.

As for the issue at hand, is module-suspend-on-idle loaded? If so, disable and unload it. Start PA with '-vvvv' switch and post the log here. You might want to try defaulting the configuration for PA, meaning delete your ~/.config/pulse. Does your GPU have a hdmi sound card?

Check if you can get sound output with PA killed through speaker-test:

speaker-test -c 8 -t wav -D plug:"dmix:{CARD PCH DEV 0}"
speaker-test -c 2 -t wav -D plug:"dmix:{CARD PCH DEV 0}"

Both should work launched in that order at the same time.

am glad to report sound's working back after another pulseaudio -k /start (i think it was 3rd one ), quickly before bothering another fellow user with this.
Sound keeps playing after rebooting the system. Uncommenting the "/etc/pulse/default.pa" config line that remap microphone to mono for Skype (as per the Pulseaudio wiki) does kill the sound back, though.

$ systool -vm relevant_snd_module

emeres you're right on that one. Sorry for issuing the last command line so lightly: / Sound working in Deadbeef I really overlooked the modules' related part. Post edited while sound's working.

emeres · 2014-09-01 19:58:59

Glad to read it is working. Can you post or link the troubling part of PAs configuration for Skype?

Is this the mono Issue you tried to fix? Why have you tried remapping it in the first place? Disabling remixing and the consequences that follow are a deliberate choice on your part, what did you try to fix initially?
