Problem with intel-hda integrated audio

Problem with intel-hda integrated audio

[Matteo Sasso]

Hello, I'm having a problem with a soundcard under ubuntu. I tried nearly 
every workaround I could find on the Internet but I have not been successful 
so far.

The computer in question is a Toshiba Satellite Pro U200 series. The soundcard 
seems to be correctly identified by ALSA but it seems muted, nothing I tried 
seems to work. I followed the instructions given at
http://www.mjmwired.net/kernel/Documentation/sound/alsa/ALSA-Configuration.txt
I determined that my card uses a AD1981 codec, so I added the following 
to /etc/modprobe.d/alsa-base:

options snd-hda-intel model=toshiba

I tried many other combinations (3stack, basic, laptop), with and 
without "position_fix=1". I also tried using underscores instead of hypens 
("snd_hda_intel"). I run update-initramfs -u after every try.

lspci -vn has to say the following:
00:1b.0 0403: 8086:27d8 (rev 02)
        Sybsystem: 1179:0001
        Flags: bus master, fast devsel, latency 0, IRQ 23
        Memory at 50080000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: [50] Power Management version 2
        Capabilities: [60] Message Signalled Interrupts: Mask- 64bit+ 
Queue=0/0 Enable-
        Capabilities: [70] Express Unknown type IRQ 0

I'll keep tabs on this mailing list, so feel free to ask for more info.
Any help is appreciated.
Thanks.

IF this is the same issue as previously posted in alsa-user, then i have
an idea what may be going on.  Try rebooting the system with "acpi=off"
in the kernel boot parameters.  If this makes audio work, you have an
issue with your acpi tables.

Could you also download and run alsa-info.sh from
http://alsa-project.org/ Help to debug section?

Hey, that worked like a charm! I didn't know ACPI could do that, so it didn't 
cross my mind to try fiddling with anything else other than the ALSA driver.

Thanks a lot, Tobin! ;)
