[SOLVED] No audio in Firefox through integrated speakers

Hello everyone,

as it is my first post in the forum I want to compliment all of you who spend so much time supporting newbies like me.

I am using Arch Linux  on a Vaio Pro  for a while now and everything is fine for me but running videos or audio streams (Flash and HTML5) in Firefox. Any other Program I tried (Epiphany, Midori, VLC, Totem, Rhythmbox, Gnome sound test) work fine. Also Firefox sound works through HDMI connection but not on my PCH sound card.

I already tried changing the default sound card via

# /etc/modprobe.d
options snd_hda_intel index=1,0 

with success – sound cards are swapped (as recognised in alsamixer --> F6). According to this and that thread it solves the issue but in my case Firefox is still mute (bound to HDMI sound). I also depend on Pulseaudio because of using Gnome (some time ago I was messing around removing pulseaudio like implied here from Gnome but didnt get it done).
Last thing I tried was running my machine on a related distro (Manjaro Gnome live pendrive) and everything works fine. So it should be possible to get it running in my Arch install. While comparing Manjaro and my System I did not find a audio-"related" package missing in mine, so I assume the last pieces of the puzzle should be hidden in configuration.

But I haven't got any clue where to look for it.

System: Vaio Pro SVP1321C5E
some terminal output (sorry, I hope it's still readable with German locale)

Re: [SOLVED] No audio in Firefox through integrated speakers

make sure that the necessary gst-packages (namely gst-libav but including good, bad, ugly etc wouldn't hurt) are installed. output of

fuser -v /dev/snd/*

while sound isn't working in firefox would be good too

Re: [SOLVED] No audio in Firefox through integrated speakers

Hello thanks for replying...

gst-libav and gst-plugins had already been installed – except for *-ugly.

so outputs without and with *-ugly plugin:

$ fuser -v /dev/snd/*
                     BEN.        PID ZUGR.  BEFEHL
/dev/snd/controlC0:  user        648 F.... pulseaudio
/dev/snd/controlC1:  user        648 F.... pulseaudio
/dev/snd/pcmC1D3p:   user        648 F...m pulseaudio

$ fuser -v /dev/snd/*            # after installing gst-plugins-ugly
                     BEN.        PID ZUGR.  BEFEHL
/dev/snd/controlC0:  user        648 F.... pulseaudio
/dev/snd/controlC1:  user        648 F.... pulseaudio
/dev/snd/pcmC0D0p:   user        648 F...m pulseaudio
/dev/snd/pcmC1D3p:   user        648 F...m pulseaudio

Re: [SOLVED] No audio in Firefox through integrated speakers

Hey you kind of pushed my nose into the Wiki --> Pulseaudio#Troubleshooting.

It has been a bad config file.

[SOLVED]

Re: [SOLVED] No audio in Firefox through integrated speakers

Yeah that would've been my next guess after seeing that fuser outputs what its supposed to, glad you found  it yourself
