Dear all,
today I made the biggest mistake of my life I think, I upgraded from ubuntu
9.04 to 9.10.
Everything is working almost fine, but the audio is gone. If I try to boot
from the CD, there's no problem,
but when I get back to the actual system, there's no sound.
The card is recognized:
marco@marco-x41:~$ lspci | grep audio
00:1e.2 Multimedia audio controller: Intel Corporation 82801FB/FBM/FR/FW/FRW
(ICH6 Family) AC'97 Audio Controller (rev 03)
!!Soundcards recognised by ALSA
!!-----------------------------
0 [ICH6 ]: ICH4 - Intel ICH6
Intel ICH6 with AD1981B at irq 22
but not for playing audio:
APLAY
aplay: device_list:223: no soundcards found...
ARECORD
arecord: device_list:223: no soundcards found...
Also when I try starting Jack:
Could not open ALSA sequencer as a client. ALSA MIDI patchbay will be not
available.
ALSA lib seq_hw.c:457:(snd_seq_hw_open) open /dev/snd/seq failed: No such
file or directory
and there are no sound cards to select.
Any ideas?
Make sure the seq module is loaded:
modprobe -v snd_seq_midi
modprobe -v snd_seq_dummy
# maybe:
modprobe -v snd_hda_intel
# check with:
lsmod | grep snd_seq
What is the output of
cat /proc/asound/cards
and
aplay -l
(-l is a little L)
and
lsmod | grep snd_hda
