I'm involved in beta testing Gstreamer 1.x support for HTML5 under
Pale Moon (a Firefox fork). So far so good; it works. I use a QEMU VM
for some building and testing. Things work great on a real physical
machine, but audio absolutely sucks in the QEMU VM. I get an annoying
warble-stutter and the playback seems a bit slower than it should be.
The same thing also happens with mplayer playing a .wav file, so it's
definitely not a Pale Moon browser problem.
The VM gets 3 gigs of RAM (host has 8), 4 gigs of swap space, and 3 of
the host's 4 cores. Resources should not be a problem. Has anybody got
better performance? If so, what are your kernel and sound card settings?
I launch QEMU with "-soundhw hda". Here are the "make menuconfig"
kernel config sound driver settings for the Gentoo guest VM.
