Too fast video playback with HDMI output and DTS setting on

System: Fedora 18 + PulseAudio + XMBC 12 Frodo (from x86_64 intel GPU, libva support

video and audio output uses HDMI. Video plays too fast and audio has problems. If setting:

Settings - System - System - Audio output - DTS capable receiver

is switched off, video playback is normal and audio works.

Detailed description:

However the FLAC playback (with missing system sounds) issue still remains: but that could be nonrelated issue.

Same here with the same distro and GPU (Ivy Bridge).

I don't think switching off DTS capable receiver is the proper solution here, that downmixes your digital signal to a stereo stream and sends it to the receiver. If you have a DTS compatible receiver, you are losing functionality.

I have the same problem on Archlinux, XBMC Frodo (from packages, config options here:, Intel GPU (sandy bridge).

I have no audio on digital streams, with super fast video playback. I have PulseAudio running, which seems to be a common link amongst people with this problem (XBMC forums has a few other folks in our boat).

Killing PulseAudio fixes the issue here, however is not a solution on my system (my setup requires PulseAudio).

Attempted solution that does not work:

Debug log:

Screenshot of audio settings:

I also do not get system sounds out of XBMC.

OP, please confirm that your receiver does support DTS (therefore stereo downmixing is not a solution).

Pulse Audio and passthrough can only work if xbmc was built with --enable-pulse and even then its rather flaky. This is NOT the case with official team xbmc binaries in our PPAs and in xbmcbuntu.

Does this mean that XBMC is unsupported by devs on all platforms other than bins from PPA and/or xbmcbuntu?

it does mean that --enable-pulse is NOT recommended, because its know to not work very well atm.

Nonetheless, there were some fixes for pulse audio support since 12.0, so try with 12.2 or a git master build and report back.
