Hi,
ALSA work's fine for me, but the OSS emulation layer doesn't work.
My configuration is:
CONFIG_SOUND=y
CONFIG_SND=y
CONFIG_SND_SEQUENCER=y
CONFIG_SND_OSSEMUL=y
CONFIG_SND_MIXER_OSS=y
CONFIG_SND_PCM_OSS=y
CONFIG_SND_SEQUENCER_OSS=y
CONFIG_SND_RTCTIMER=y
CONFIG_SND_VERBOSE_PRINTK=y
CONFIG_SND_ENS1371=y
# OSS options
CONFIG_SOUND_PRIME=y
CONFIG_SOUND_BT878=y
CONFIG_SOUND_TVMIXER=y
All other sound options are disabled.
It's a SoundBlaster 128 PCI card.
I've applied the attached patch to display more meaningful
error-messages.
Kernel-log messages are:
Nov 2 15:59:27 lfs kernel: Advanced Linux Sound Architecture Driver Version 0.9.7 (Thu Sep 25 19:16:36 2003 UTC).
Nov 2 15:59:27 lfs kernel: request_module: failed /sbin/modprobe -- snd-card-0. error = -16

Nov 2 15:59:27 lfs kernel: #0: Ensoniq AudioPCI ENS1371 at 0xb800, irq 19
Lines marked with a * at the beginning are from my patch.
The failed request_module() seems to be triggered by
if (!system_running)
return -EBUSY;
in call_usermodehelper() which is called by request_module().
Why are we trying to load a module, althought ALSA is completely
compiled into the kernel? We shouldn't do it, should we?
OSS-emulation failes, because something is -EBUSY.
==> ALSA sound/core/oss/pcm_oss.c:2354: error code: -16 == -EBUSY
I've not found out, why it fails. Maybe someone has an idea?
Here's my patch:

^^^^^^^^^^^^^^^^^^^^
this conflicts with ALSA. try to pass the index parameter via boot
option of snd-ens1371.

it's already fixed on the ALSA cvs version.

Thanks for your suggestion, but it doesn't work.
Still displays
ALSA sound/core/oss/pcm_oss.c:2353: unable to register OSS PCM device 0:0
Is there some other way to make bttv-audio and
ALSA-ens1371 working both? Would be cool if I
could use both at the same time. :)

.. and so on.
Or did I misunderstand you?

the first argument is "enable". "index" is the second argument.
so, you'll need to pass "snd-ens1371=1,1"

Now neither ALSA, nor OSS-emu works. :)

hmm, you have also TVMIXER. so the ens1371 will be the third one?

I tried various numbers from 0 to (don't remember). but I did
also try 3.
