Namely, the sound would make really annoying "cracking" noises, somewhat resambling a bad radio. At first I thought it was a codec or player issue, but it turned out to not be the case. A cry for help on mplayer-users resulted in this reply: "it is a FreeBSD related problem. For the 4.X branch it was a problem with the kernel software mixing which runs to 44100 Hz and most of movies are encoded to 48000 Hz, so the nasty sound appears." Apparently, this problem is also present in 5.0 >How-To-Repeat: install mplayer attempt to play a video with sound encoded at 48000 Khz >Fix: There is no real fix so far, but the workaround is to pass "-srate 44100" to mplayer or gmplayer when starting them. Yes, I know it's very ugly, but it's better than having nothing until the real fix arrives. >Release-Note: >Audit-Trail: >Unformatted: "device pcm" To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the messagehelp
