Thanks for the suggestion. I tried, but could not get any sound at all (either via HDMI or spdf cable) when I set audio output to "plug:iec958". However, the video did seem to play at the correct speed!

Is this due to design of the video player? I have these speed issues as well since I am using iec958 as the output. I am doing this since I want bit-perfect playback of my music and playing music at 44.1kHz works perfectly (I even see my receiver acknowledging the stream at 44.1kHz).
I am also using passthrough.

AFAIK its passthroughs fault, it only accept a certain samplerate and DVDPlayer (our video player) is using the videos audio samplerate, which can vary and be whatever the source says. The PAPlayer (our musicplayer) is resampling everything to 48000. The usual behaviour of the OS is to resample every audio that is passthrough to fit the samplerate, so it does the conversion from 22khz to 44.1khz incase its needed. XBMC does not leverage this currently. I have no clue why as Im not that good with ALSA. Although we are in the process of sketching out and designing so XBMC is able to do that conversion on both players if its needed.
This feature is hopefully available in 9.04
