Subject: Request for advice on stopping xruns
Date: Wed, 06 Mar 2002 08:50:28 +0000 [thread overview]
Message-ID: <3C85D854.484BF9EF@solid-state-logic.com> (raw)
Hi, I'm developing an 8 channel recorder based on alsa0.9.0beta10 and a
Terratec EWS88mt sound card.
I'm now using a 2.4.18 kernel with the Andrew Morton patches applied. I
really want to be able to record/playback at the full 96k 24bits on all
8 channels simultaneously, but I need absolutely no under/overruns.
Currently, as I try to up the bandwidth requirements I get xruns
occurring more and more frequently; I'm not even sure if I can guarantee
a maximum, before the onset of xruns, although 16bit 44.1 may well be
okay.
I don't care about other system processes, so I've set the record and
playback threads to SCHED_FIFO prio 99 (although I don't really know if
this is the right thing to do!)
Is there anything I can do/change/not do to eliminate xruns altogether?
Thanks,
Fergus
