Hi Dominique:
1) hotplug isn't running.
If you have udev, hotplug is always running. And udev is the standard these
days.
2) A little more clarification: when I run alsamixer (on the occasions
when it works) it only shows the Master; but on the occasions when it
stops working, a mysterious "SPDIF" setting is available (with the
Master as well).
Sounds like two different sound cards are in contention.
3) If I run /etc/init.d/alsasound restart on a bootup when it
works--it will go from working to not working. But, randomly, it will
start to work again only on a
reboot.
4) I am now using vanilla gentoo 1.0.11 alsa-driver and alsa-utils for
testing with you. With 1.0.13 (gentoo), I get a different error, but
with 1.0.13 compiled by hand, it has the same effect. Besides, it
WORKS atleast once in a while with 1.0.11, so I figured I'd stick with
the vanilla gentoo, until I need to move beyond.
5) here is my lsmod:
snd_pcm_oss 31328 0
snd_mixer_oss 13888 1 snd_pcm_oss
snd_seq_oss 26624 0
snd_seq_device 5384 1 snd_seq_oss

snd_page_alloc 6856 2 snd_hda_intel,snd_pcm
That is not lsmod, but I assume it is all of the entries which start with
snd. ARe there perhaps some old oss modules being loaded as well?
(Unfortunately, this is lsmod on a broken sound bootup; I didn't get
a chance to lsmod on a working sound setting -- even though the
/etc/modules.d/alsa remain the same between the two.)

If you want to use the alsa-driver packages with gentoo, you must not have alsa

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.
It can be the case if you have an USB sound card as a webcam. The
snd_usb_audio will be loaded by hotplug before at alsasound load the alsa
modules, and the regular sound card will be the second sound card.
If it is the case, you have to add
"snd-usb-audio" (without the double quotes) in /etc/udev/blacklist and alsasound
will work as expected.
If it not solve the problem, what is the output of
lsmod|grep snd
Dominique
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!
