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.t... 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.
