Nice :) And as expected it uses less CPU than alsa_in and alsa_out. I tried alsa_loopback from zita-alsa-pcmi this morning (as "./alsa_loopback hw:1 hw:1 48000 2048 10"). No errors, no crashes, but no output on the soundcard. Last line printed is "synced". However, the documentation is sparse so I didn't know what all these parameters are for and guessed most of them. The ajbridge has the same problem. There's the quality-parameter that defaults to "48" but that's all I get to know about it. No value range, no indication whether 0 is better or worse than 1000. You could add some hints to the readme ;) But thanks for all your work you contribute to linux-audio and your support :) Jannis _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
