The pnp sbc driver finds the ess sound card and attaches pcm. However, the sound sometimes (> 50%) comes out as static. Perhaps there is something funny required to initialize or set the mode for the card? >How-To-Repeat: That is the tough one. It occurs seemingly at random; if if works, it seems to stay working while the device is open, but may fail on the next use. KDE seems to be more likely to fail that pcmplay, but KDE often works. suspend/resume kicks the card, so it may start or stop working as well. >Fix: Unknown. Is there anything I can do to help track down the problem? >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
