[LAU] Other crackles

Hello all, The thread on 'crackles in audio' reminded me of a similar problem which upset me for some years now. I normally run Jack all the time, and for apps that don't support it there's an ~/.asoundrc like this: pcm.!default { type plug slave { pcm "jack" } } pcm.jack { type jack playback_ports { 0 zita-mu1:in_2.L 1 zita-mu1:in_2.R } capture_ports { 0 system:capture_1 1 system:capture_2 } } If you don't know what zita-mu1 is, see here: <http://kokkinizita.linuxaudio.org/linuxaudio/zita-mu1-doc/quickguide.html> The only use case for this is viewing youtube videos with either Chromium or Firefox, which will use ALSA's default device. This works ok but after some time I get 'crackles'. It sounds like a buffer wraparound. Repositioning or stopping/restarting the video usually solves the problem, but it will come back after some time. I see no reason why things shouldn't 'just work'. And I've been wondering: is this a long-standing problem with ALSA's Jack plugin, or are the browsers doing something wrong ? In either case, is there a solution (not involving PA or loop devices) ?
