No sound in non-root user

noarch · 2015-05-02 08:29:42

Hi All,

Yesterday, I had to hard-reboot my laptop and some files got corrupted I guess. Now, the sound doesn't play anymore from the non-root user. But sound does work if I log into root user.

[cheema@screwed ~]$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: MID [HDA Intel MID], device 0: 92HD87B1/3 Analog [92HD87B1/3 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: MID [HDA Intel MID], device 3: ID 2804 Digital [ID 2804 Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I tried tweaking my ~/.asoundrc . The original file looked like this

# ALSA library configuration file

# Include settings that are under the control of asoundconf(1).
# (To disable these settings, comment out this line.)
</home/cheema/.asoundrc.asoundconf>

If I replace the contents of the ~/.asoundrc, then the sound does work(somewhat).

pcm.!default {
        type hw
        card MID
}
 
ctl.!default {
        type hw
        card MID
}

In this case, only one application is able to play the sound. For ex, if I run speaker-test and afterwards launch Clementine, clementine gives the error

Could not open audio device for playback. Device is being used by another application.

No such blocking occurs if I run from root user.

I'm attaching other debug info that may be helpful. Alsa config file /home/cheema/.asoundrc.asoundconf (This is same as /root/.asoundrc.asoundconf)

# ALSA library configuration file managed by asoundconf(1).
#
# MANUAL CHANGES TO THIS FILE WILL BE OVERWRITTEN!

# Manual changes to the ALSA library configuration should be implemented

Any ideas?

What do you mean "the original"? Where did that original come from? There is no "original" or default for this file in archlinux. This all reminds me a lot of this previous thread. Are you using an AUR package to "autoconfigure" alsa? Can you post the output of the following command:

uname -a

noarch · 2015-05-02 11:06:04

Trillby,

[cheema@screwed ~]$ uname -a
Linux screwed 3.19.3-3-ARCH #1 SMP PREEMPT Wed Apr 8 14:10:00 CEST 2015 x86_64 GNU/Linux

I do remember using asoundconf-gtk, asoundconf to create the ~/.asoundrc.asoundconf file, but I did not edit it thereafter. I'll try the suggestions in the other thread.

Thanks for the suggestion

Generally no ~/.asoundrc (nor other such file) is needed. So I'd suggest just removing all of that and starting from scratch following the wiki if it doesn't work without any configs.
