Yes.
If you edit /usr/share/alsa/pcm/dmix.conf and change the number of periods it
uses. The default here is 16. Try 4 instead.
Here's an excerpt from the default dmix.conf I have here:
periods {
@func refer
name {
@func concat
strings [
"cards."
{
@func card_driver
card $CARD
}
".pcm.dmix.periods"
]
}
default 16
}
Changed the 'default 16' to 'default 4'. This will reduce the number of
buffer used and so latency involved with using the dmix plug-in - but it'll
likely increase the CPU load.
However, if the ALSA OSS emulation causes the same stuttering for you, then
the problem isn't dmix, IMHO. The OSS emulation doesn't use this
configuration mechanism (it doesn't use dmix or any other libasound
plug-ins).
Cheers,
Rich
