The test opens the same device for both capture and playback (the same device being both default input and output), and OSS won't have it (hence the error on line 1459).Arve
1. The device DOES support full duplex. 2. Even if it wouldn't, crashing like this is not very nice. :-) Matthias ------- Matthias Brennwald Lägernstrasse 6 CH 8037 Zürich +41 (0)44 364 17 03 address@hidden
