Yes, if I listen a song with a multiple of 1000, subjectively seen, then the clicks are gone. > But I think, this problem basically is solved with newer ALSAs.

Only on great (de-)compressing-jobs I get this effects on an higher level. Compilation of greater sources works without sound-problems. Maybe I should decide between two various kinds of "clicks" :-) > Hm, I'm puzzled. I actually have no idea why OSS is muted, when ALSA > is playing just fine.

I recompiled kernel, and alsa-oss('ebuild' for oss support in alsa) serveral times, without any effect. But I recognized two new events. The first one is: Sometimes, if oss is the sound-device in amarok, then I can hear "the song" like played in a few seconds. The other is a modinfo: modinfo snd_pcm_oss filename: /lib/modules/2.6.22-gentoo-r8/kernel/sound/core/oss/snd-pcm-oss.ko alias: sound-service-?-12 alias: sound-service-?-3 license: GPL description: PCM OSS emulation for ALSA. author: Jaroslav Kysela <perex@xxxxxxx>, Abramo Bagnara <abramo@xxxxxxxxxxxxxxxx> depends: snd,snd-pcm,snd-mixer-oss vermagic: 2.6.22-gentoo-r8 SMP mod_unload PENTIUM4 parm: dsp_map:PCM device number assigned to 1st OSS device. (array of int) parm: adsp_map:PCM device number assigned to 2nd OSS device. (array of int) parm: nonblock_open:Don't block opening busy PCM devices. (bool) Are the lines "alias: sound-service-?-12" ( ?... ???), and "parm: nonblock_open:Don't block opening busy PCM devices." normal? I also removed xine-configurations, and tested oss-device as root. No achievement. And on "cat /dev/urandom > /dev/dsp" I get "bash: /dev/dsp: Das Gerät oder die Ressource ist belegt"(Device or resource is busy). But fuser -l says it's empty. Could a debug of runlevel-alsa be helpfull (With my layeyes I couldn't find something interesting)? by then Happy Easter, Jan ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
