greetings! my T520 (combo jack) works fine with headphones. i've never tried plugging a mic into that jack, but the internal mics work fine. i always use an external interface for recording anyways... i'm on Crunchbang (Debian). cheers! .pltk. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
