I tried recompiling my kernel without pre-emption, but it made no difference. I've left it off for the time being. I tried recompiling the mjpegtools, and that made no difference. I've had the mjpegtools working fine on this machine previously using the OSS, as opposed to ALSA which it now uses, so I tried pulling ALSA out and putting the deprecated OSS drivers back in. I got into kernel module dependency hell, so I backed out of that route. I presume it shouldn't make any difference.

'arecord' and xawtv's 'record' utility run OK, and I can hear the sound via the line-in as it's recording, but playing back the resultant WAV file results in silence. I can't get anything from the microphone input either. That used to work. > Maybe you can try to use the read mode.

You're spot on here: using -a 0 stops the lavrec capture getting upset. The only drawback is, well, no sound! I did find something interesting though: the first lavrec capture I do after a reboot works correctly. The sound doesn't come out with the pulsing and the video doesn't stop recording. I've tried it several times with an 'rcalsasound restart' in between and each time it works fine. The first time I tried a second capture without resetting the sound system: crackle, crackle, crackle... <A bit later...> In fact, the problem seems to be with glav. I reset the sound system and recorded several clips, one after the other with no resets. I then play them back using glav and they're all perfect. I record one more and it comes out with crackles. I reset the sound system and play it again - it still crackles. I appears that glav exits leaving the sound system in a state where lavrec records sound incorrectly until the sound hardware is reset. Is that possible? ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
