I went back to a 2.4 series kernel and the sound is perfect, but, of course, the emulation for qemu is now ~much~ slower *sighs* (I didn't realise just how much of a performance boost 2.6 was giving me!). Ah well, can't have everything, can we? :) Alsa sound works perfectly in 2.6, but myself not really understanding the audio code in qemu at all and not being particularly familiar with alsa I'm afraid that I'm not the person to try coding up an output driver for it... :-/ *looks around hopefully* ;) D On Fri, 2004-08-13 at 17:05, Darryl Dixon wrote: Malc, Definitely seems to be something wrong with my setup; with QEMU_AUDIO_DRV set to either oss or sdl I get no output, but if it's set to wav the qemu.wav file is generated correctly and upon playback contains the correct sounds...
