I am having a few problems with newpcm. I often play a whole bunch of Sesame Street AVIs to keep the 1 and 3 year olds happy while I read email. I usually play them like so (straight from the CD-ROM): foreach blah ( /cdrom/letters/tv/*.avi ) xanim -Zr +Ze +Av`mixer | grep pcm | cut -d: -f2` $blah >& /dev/null end This worked fine with the old sound drivers but now I find that I have to put in a 1 second sleep after xanim or the sound will usually stop completely after the first AVI. I am also now getting the following messages on the console: "dsp sync" I get 4 of these at the start of each invocation of xanim and then I get 1 at the end of each invocation of xanim. When the sound has stopped completely I have to reboot to get it back. My -CURRENT is about 3 days old.

The most recently updated file in /usr/src/sys/dev/pcm for me is channel.c at version 1.3 if thats usefull.
