LinuxQuestions.org - [SOLVED] Alsa sound problem

Hello. My sound stopped working.

Code:

$ aplay -l

aplay: device_list:240: no soundcards found...

But:

Code:

$ sudo aplay -l

**** List of PLAYBACK Hardware Devices ****

Home directory /home/georgii not ours.

card 0: Intel [HDA Intel], device 0: ALC662 rev1 Analog [ALC662 rev1 Analog]

  Subdevices: 1/1

  Subdevice #0: subdevice #0

Same with alsamixer:

Code:

$ alsamixer

cannot open mixer: No such file or directory

But:

Quote:

$ sudo !!

shows me the mixer.

Anyway, the sound is just gone. When I do:

Code:

$ ubuntu-bug audio

ERROR: symptom script /usr/share/apport/symptoms/audio.py crashed:

Traceback (most recent call last):

  File "/usr/lib/python2.7/dist-packages/apport/ui.py", line 56, in thread_collect_info

    package = symb['run'](report, ui)

  File "/usr/share/apport/symptoms/audio.py", line 187, in run

    package = check_pulseaudio_running(report, ui)

  File "/usr/share/apport/symptoms/_audio_checks.py", line 80, in check_pulseaudio_running

    return set_title(report, 'pulseaudio', 'Pulseaudio is not running')

NameError: global name 'set_title' is not defined

It says: "PulseAudio seems to have crashed. Do you wish to report a bug?", then crashes.

Any help appreciated.
