Swapping in the sound directory from 'cvs co -D "July 31, 2001 12:00pm" sys_dev_sound' fixes the problem, and write returns normally. I saw a discussion on the FreeBSD newsgroup about this problem occuring in 4.4-PRERELEASE and this confirms that the problem still exists in 4.4-RELEASE. >How-To-Repeat: Install Open Mash from cvs (instructions at http://www.openmash.org/developers/cvs/unix.html) on a FreeBSD 4.4-RELEASE machine with sound compiled into the kernel. Use a Yamaha OPL3-SAx sound card (or possibly any other half-duplex only card) and try to receive audio from a multicast session using vat. vat will appear to hang, but it is actually caught in a loop trying to write audio because write() is returning -1. >Fix: Revert to the old /src/sys/dev/sound code. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
