Greetings all,

Every time a qemu instance is run, the host systems audio hardware sample rate 
is set to 44.1khz. Is it possible to change this behavior, and if so, how?

 Hi,

not sure if I've got the question right, and I'm not an expert when it comes to QEMU audio, but I think you can set the playback frequency like this for example:

 qemu-system-x86_64 --audiodev alsa,id=a1,out.frequency=48000

... but seems like the QEMU documentation is really lacking here, so I might be wrong. Maybe Christian, Gerd or Marc-André could correct me in that case (now on CC:).

 HTH,
  Thomas
