Changing hw.snd.pcm0.buffersize in 4.10.

[Sandy Rutherford]

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
