[linux-audio-user] noacpi, no sound

[Atte André Jensen]

Hi

I have glitches in my audio every 30-60 secs or so, so I thought I'd try 
  disabling acpi and see what happens. I added this to my 
/boot/grub/menu.lst:

title           Debian GNU/Linux, kernel 2.6.15-1000hz noacpi
root            (hd0,0)
kernel          /boot/vmlinuz-2.6.15-1000hz root=/dev/hda1 ro pci=noacpi
initrd          /boot/initrd.img-2.6.15-1000hz
savedefault
boot

It's an exact copy (except the name and the pci=noacpi) of my working 
entry. After booting using this, jack (I use qjackctl) won't start, this 
is what I see in the messages window:

This is my .jackdrc:
atte at ajstrup:~$ cat .jackdrc
jackd -R -P70 -dalsa -dhw:0 -r48000 -p256 -n2 -S

Moreover xmms fails with:
** WARNING **: oss_open(): Failed to open audio device (/dev/dsp): No 
such file or directory

So something seems all messed up with my sound card (at least it doesn't 
seem to be available), although the modules does get loaded:

Any idea what's wrong?
