Hi Qiang, thanks for the info. But I'm not really sure what I can do here. I don't use xserver-xorg-video-qxl as I'm using a Windows guest with the win qxl driver. On the thin client there's an Ubuntu 14.04 running using some intel driver as it's a Celeron based board. Also I didn't find the patched file you were mentioning. I guess it's part of xserver-xorg-video-qxl, right?

Everything goes fine. Please make sure your code include this patch: http://lists.freedesktop.org/archives/spice-devel/2014-April/016645.html Opus requires a frequency of 48000; it will not operate at 44100 If you want to know which codec is used, you need to enable debug. Try to print more log like; sin->st->frequency = SND_CODEC_CELT_PLAYBACK_FREQ; /* Default to For client make sure the client_can_opus=1 snd_codec_is_capable is True Hope it can help you.
