Takashi,
Sorry for the delayed answer. I tried both by patching my yesterday 
snapshot, and by using the new snapshot, neither of them worked 
completly right.

Good part is that now I can decide if I either want to turn on or off 
the bloody beep. But result is the same on both cases, no matter if it's 
on or off it doesn't make a beep (which is pretty good for my ears, but 
not for the code purspose).

I now compiled with --with-debug=full (sorry I didn't do it before, 
actually I compiled with  -O0 -g to figure out the memory leak, but 
forgot to enable printk debugging), I send two dmesg logs, one is 
without telling hda-intel which model to use, the other one is by 
passing model=dell-m42. I'm also attaching alsa-info.sh output for 
model=dell-m42.

I'll take a look at the code tomorrow too see if I can figure out why it 
doesn't beep at all.

Cheers,
Manuel
