Since about an hour I have a new problem: no sound at all! It happened
before I had the chance to change any options. Now I've appended
"model=toshiba" (as suggested elsewhere) but it didn't help. However, I
noticed that alsamixer doesn't show a control for the "Master" device
(only PCM, Mic and Beep). And it also doesn't show any "Capture" devices
(this is independent of the "model" option) although they seem to exist:
a...@andicompi:~$ cat /proc/asound/devices
2: : timer
3: : sequencer
4: [ 0- 0]: digital audio playback
5: [ 0- 0]: digital audio capture
6: [ 0- 6]: digital audio playback
7: [ 0- 6]: digital audio capture
8: [ 0] : control
a...@andicompi:~$ cat /proc/asound/cards
0 [SB ]: HDA-Intel - HDA ATI SB
HDA ATI SB at 0xd0000000 irq 16
And I also noticed two devices called "Caller1" and "Off-hook" that
remind me of a modem. There is indeed a modem built into this laptop and
"cat /proc/asound/card0/codec#0" shows this:
Codec: LSI Si3054
Address: 0
Function Id: 0x2
Vendor Id: 0x11c13026
Subsystem Id: 0x11790001
Revision Id: 0x100700
Modem Function Group: 0x1
The ALC861 is in "codec#3".
@Daniel : I also have that "switching to single_cmd" error in my dmesg
now. Is there an option to choose the codec slot or interrupt? I
searched the ALSA documentation but found only the "index" and
"probe_mask" options that seem to be related to this problem. If you'd
tell me which options I should try I would post my results! Currently,
my alsa-base.conf looks like this:
# Prevent abnormal drivers from grabbing index 0
options bt87x index=-2
options cx88_alsa index=-2
options saa7134-alsa index=-2
options snd-atiixp-modem index=-2
options snd-intel8x0m index=-2
options snd-via82xx-modem index=-2
options snd-usb-audio index=-2
