Hi,
I've had quite a headache with the snd hda intel driver. Below is my
lspci. I am using GENTOO (latest) on a brand new Gateway MX6920
Laptop. With alsa-utils-1.0.11 and 2.6.17-gentoo-r8 with
SND_HDA_INTEL compiled in AS A MODULE (It did not work compiled in
directly to the kernel; nor did it work with alsa-driver-1.0.11--by
"did not work" I mean everything ran fine, but no sound came out--) it
worked every few reboots; in other words, it was very random. The
curious thing about "alsamixer"--when it worked it only presented one
control option (Master), whereas when it didn't work there were two or
more controls.
I also tried: (a) compiling alsa-utils-1.0.13 and alsa-driver-1.0.13
(and alsa-lib and alsa-header) directly from alsa-sound.org. But then
I get an ioctl error or other strange errors (it sometimes crashes,
sometimes (e.g., mplayer) will say that the sndcard isn't fast enough,
sometimes (madplay) an ioctl error). So I tried (b) emerging the
1.0.13 ebuilds of alsa stuff. Ditto error message.
So, in summary, only the MODULE version of snd hda intel worked
(kernel 2.6.17-gentoo-r8). But it only worked every few (random)
reboots; when it worked, it worked fine.
If you want more information, please let me know!
