You can play and record 48KHz/16bit/2ch sound format only, if your chip don't have it. 3) When I/O load is heavy, it causes 'play interrupt timeout', and can't continue playing. * HOW TO INSTALL 1) download ich.c.gz(6632Bytes, MD5:edc8cda20a9330ffd8ad56cd850a43ad) http://www.katsurajima.seya.yokohama.jp/ich/ich.c.gz 2) extract and copy to src tree. gunzip ich.c.gz cp ich.c /usr/src/sys/dev/sound/pci 3) append following line to /usr/src/sys/conf/files. dev/sound/pci/ich.c optional pcm pci 4) build kernel and install (if you want to specify configfile, KERNEL=<your config file>) cd /usr/src make buildkernel make installkernel To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
