Hi,
I have HP vt6200 notebook. It has ALI5451 chip. I tried diffrent kernels
2.4.18, 2.4.19, 2.4.20rc1, 2.5.48 and alsa-driver 0.9rc4,rc5,rc6.
The standard kernel trident module works OK on all kernels but alsa driver
does not on any.
Before rc6 the snd-ali5451 module would just hang with "(initi

I asked Paul once about the matrix mixer.
His answer was :
first value: input source
second value: output source
third value: gain
input source: 0-25 (physical channels), 26-51 (audio output streams)
output source: 0-27 (physical channels)
output channels 26 and 27 a

well, the basic premise is simple... the speaker wires have a positive and
negative wire, current flows through the coil, and the cone moves one way or
the other. If you swap the wires, the cone moves the other way. Inaudible,
except that if the two speakers aren't moving the same way, they wa

Hi Kai,
thank you. You are right: my ide-dma is turned off. I only activated it in the
SUSE setup, but I've never check if it is really switched on.
Unfortunately I can not turn on the dma:
linux:/home/woody # hdparm -m 8 -d 1 -u 1 -c 1 /dev/hda
/dev/hda:

Things get much clearer now, thank

Has anyone else seen a kernel panic when unplugging a busy (i.e.

I'll send my ksymoops output in a bit... Just wondering if this is just

Dear developers,
I am going to write a sound device driver based on Linux Kernel 2.4.18.
After collecting data from web and Kernel 2.5.x. I found ALSA.
I would like to know where should I start to know ALSA ?
What's the architecture of ALSA in linux.
Regards,
Alamy Liu
