I got alsa working with the new kernel, but there are two questions
remaining:
1. Automatic alsa start:
Unlike with former kernels, the alsa-driver doesn't get loaded
automatically when it is used by an application (I have configured the
driver supplied with the kernel source). I have to issue
modprobe snd-ice1712 or
service alsasound start
to get alsa going (Redhat 9 system).
2. Proper location of alsa-driver in kernel source tree:
I'd like to merge a more recent driver into the kernel source (in
linux-2.6.0 from kernel.org there's version 0.9.7). Following Jaroslav's
advice from a recent thread, I'd copy the contents of, say
alsa-driver-1.0.0rc2/alsa-kernel
to
/usr/src/linux-2.6.0/sound.
But in the former directory (alsa-kernel) there is a subdirectory
/include which isn't in the latter (sound).
Should the contents go to
/usr/src/linux-2.6.0/include/sound/ ?
TIA
Klaus
Yes exactly.
Well, I dared to copy over the rc2 files as indicated; moreover I moved
the /Documentation directory to its place in the kernel source.
Result: The kernel compiled without any errors (attached you find the
sound portion of my .config file). Even the snd-modules loaded
automatically when I opened an application (AlsaPlayer).
- BUT: The sound is terribly distorted, all bar graphs for PCM Out in
envy24control are to their limit.
So I started from a fresh linux-2.6.0 kernel source and recompiled the
kernel ---> nice sound again, but of course coming from driver version
0.9.7 supplied with the kernel.
Finally, I compiled alsa-driver-1.0.0rc2 seperatly from the tarball.
Sound is nice when restarting the rc2 driver, but after a reboot:
distortion again.
So one might conclude: alsa rc2 and kernel 2.6.0 don't go together very
well ...
