It is only lavplay/glav that does not reproduce the recorded sound. Playing the same clip with mplayer has good sound and video. lavplay/glav has good video but only a short click or pop in the beginning then no sound. Subsequent rewound and play in glav remains silent. Here is thte output of glav with -v 2: There is nothing relevant in /var/log/messages. [EMAIL PROTECTED] ~]$ glav -v 2 +n -U -a 1 test.avi ++: INFO: [lavplay] Norm set to NTSC ++: INFO: [lavplay] Initialising SDL ++: INFO: [lavplay] SDL YUV overlay: hardware ++: INFO: [lavplay] Using read(2)/write(2) system call for capture/playpack ++: INFO: [lavplay] Output norm: NTSC ++: INFO: [lavplay] Output dimensions: 720x480 ++: lavtools version 1.9.0 ++: ++ WARN: [lavplay] Unable to set negative priority for audio thread. ++: ++ WARN: [lavplay] Pthread Real-time scheduling for audio thread could not be enabled. ++: [EMAIL PROTECTED] ~]$ I checked settings in alsamix and aumix and they both have volume pcm not muted. My kernel is 2.6.20 (compiled by myself) with alsa, and it has oss emulation; mplayer can play the clip with alsa or oss configuration. I hope this helps, and thank you for your interest in solving this quandery.
