Is it possible to change the sysctl variable hw.snd.pcm0.buffersize (DMA buffer size for the soundcard) in FreeBSD 4.10? I know that in 5.x this is changed in devices.hints. I'm guessing that something in the kernel config file will do the job, but haven't been able to figure out what.
I am trying to increase the buffersize to get rid of little skips in the playback, which I believe are caused by underruns.
Thanks, Sandy

} In FreeBSD 5.3 you can change the buffersize by adding
} hint.pcm.0.buffersize="foo" to /boot/loader.conf, have you try'ed this with 4.x?
I wonder if it wouldn't be:
set hw.snd.pcm0.bufffersize=N
in accordance with other variables in /boot/loader.help.
OTOH, there was a note in
/sys/i386/isa/sound/sound_config.h
(as of March) that refers to using "make config" to change the DSP_BUFFERSIZE constant during, I assume, the kernel build operation. As I didn't start using FreeBSD on the desktop until 5.2 came out, I can't say that this is in anyway authoritative, and possibly isn't even helpful, though....
