 I upgraded my laptop to -current
 
 rival@mubutu:~ $ uname -a
 NetBSD mubutu.no.phear.org 3.99.6 NetBSD 3.99.6 (MUBUTU) #3: Tue Jun 21

 digging into this sound problem i found out this page :
 
 http://www.unixmagic.org/ml/netbsd/200308/msg00011.html
 
 remembering the linux alsa note in their bugtracking tools and remarks 
 from user that the external amplifier must be switched off.
 
 I tryed to add this according to the webpage
 (which is basically the line Tamura Kent sent to me which is in the PR 
 29842)
 
 to dev/ic/ac97.c line 1117 :
 [...]
 __KERNEL_RCSID(0, "$NetBSD: ac97.c,v 1.75 2005/05/30 04:43:46 christos 
 Exp $");
 [...]
 ac97_setup_defaults(as);
 +host_if->write(host_if->arg, AC97_REG_POWER, AC97_POWER_EAMP);
 
 if (as->type == AC97_CODEC_TYPE_AUDIO)
 [...]
 
 and after reboot the sound suddently worked out.
 Can i help more by making it clean and adding like
 external setup mixerctl/audioctl/sysctl ?! for those kind of chipset.
 
 or may be it's enough.
 
 Hope it helps,
 Best Regards,
 Eric.
