I''ve been trying to get a (Windows) HVM DomU to play sound through my PC''s speakers (and hopefully microphone input from my PC''s microphone too). I''m using an ac97 emulated by qemu-dm, but qemu-dm is trying to us OSS for sound output, which isn''t working. In /var/log/xen/qemu-dm-win.log I get messages like: oss: Could not initialize DAC oss: Failed to open `/dev/dsp'' oss: Reason: No such file or directory audio: Failed to create voice `ac97.po'' Running /usr/lib/xen-4.1/bin/qemu-dm-orig -audio-help seems to imply that Xen''s version of qemu only supports oss or wav generation. I have tried replacing /usr/lib/xen-4.1/bin/qemu-dm with a script that calls the original qemu-dm using alsa-oss, as follows: aoss qemu-dm-orig [options] But the above OSS errors are still appearing. I could pass my real PCI sound card through but I''d still like sound from my Dom0 to be played, which rules that out. FWIW I''m on Linux Mint12. Has anyone had any luck getting sound out of a DomU?
