DO you know which app causes them ? (and yes, the driver should probably return a failure rather than just print and assume that it succeeded). can you tell me which version of the driver are you using (cat /dev/sndstat if you don't know). > These messages usually only show up during fairly heavy system load (i.e. > when I'm doing a lot in X and the system is swapping, and I also have > timidity playing a MIDI file or am playing a game that uses sound). Maybe > this has something to do with it? maybe there are missed interrupts which cause the dma timeout and following error messages that you see... some cards (e.g. the OPTI931) seem to have problems with missed interrupts (and the driver implements some workarounds), but the Vibra16C i have seems to behave reasonably well... cheers luigi -----------------------------+-------------------------------------- Luigi Rizzo | Dip. di Ingegneria dell'Informazione email: luigi@iet.unipi.it | Universita' di Pisa tel: +39-50-568533 | via Diotisalvi 2, 56126 PISA (Italy) fax: +39-50-568522 | http://www.iet.unipi.it/~luigi/ _____________________________|______________________________________ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
