 |
|
Something is blocking my audio device. Is there an easy way to find out what? I got this problem after a recent "emerge -DuvaN world". I've been looking around the forum for anyone with with a similar problem, but none fits mine. Neither XMMS or Mplayer can use the audio device. I've checked output plugins etc. but they seem fine (set to ALSA).

MdaG,
A few basic checks are in order. Have you done etc-update after your emerge world ?
Are you in the audio group run the command.
What is in /dev/snd and /dev/sound ?
list them with ls -l so I can see all the permissions too.
Did your /etc/modules.d/alsa get overwritten by a careless etc-update ?
Are your channels unmuted and sliders pushed up in alsamixer?
Only Master and PCM are needed for playing sounds from your hard drive.

I'm in the audio group (the sound has been working for the last five months).

I ran dispatch-conf (not etc-update) after updating my system.
I cannot recall overwriting my /etc/modules.d/alsa
| Quote: | $ ls -l /etc/modules.d/alsa
-rw-r--r-- 1 root root 1100 May 16 08:39 /etc/modules.d/alsa |
My channels are unmuted and I'm only using Master and PCM.

By the way, today when I updated my system there were some files that needed updating. When I ran dispatch-conf I got the following error message:
| Quote: | # dispatch-conf
diff3: subsidiary program `/usr/bin/diff' failed (exit status 2)
diff3: subsidiary program `/usr/bin/diff' failed (exit status 2)
diff3: subsidiary program `/usr/bin/diff' failed (exit status 2) |
I then tried it a second time and it went through. I tried searching on the forum for similar string, but none came up. Oh, well tomorrow I'll know if I can boot my machine or not

MdaG,
The sound things all look good.
You can try running Thats list Open Files and see what (if anything) has the sound special device files open.

I'm running Gnome (latest stable) and my default sink is ALSA. I've never understood why esd (isn't that enlightenment?) keeps getting mentioned... ? |

MdaG,
esd is the GNOME sound daemon. Its captured all your sound devices, so nothing else can use them directly.
Instead, all sound must be routed through esd.
Turn off the sound server is GNOME Desktop -> Preferences -> Sound. Uncheck Enable software sound mixing.
You may have to restart GNOME

Ah, sweet! Thank you! It worked! 
How come it worked before with the sound server startup enabled at startup ? |

MdaG,
Your applications probably made sounds through esd, which provides software mixing.
