PC Applications 'loose' speakers after SPDIF

[ginjaninja]

Ati Radeon HD 5850
Latest Catalyst HDMI Audio driver 040611
Onkyo TXNR808

Windows 7 64bit configured to use AMD HDMI with 5.1 speaker config.
MPC-HC 64bit configured to use SPDIF 16bit for AC3 and DTS

Symtom
When ever i play an AC3 or DTS enabled media, the av receiver switches to correct mode on the LCD panel. However the PC and the appications loose speaker connectivity when i play DD/DTS media...Skype displays error 'lost soundcard' and other applications have no volume/output. I have to close the movie playback, move the receiver back to multichannel mode and restart the windows app.

Is there a way to make windows audio carry on working whilst the av receiver is switched into Dolby D / DTS mode?

Maybe i need to go to the trouble of having a separate 'normal' sound card for general OS and only use HDMI/SPDIF for movies? and hook up normal sound to the av receiver on a different input.

thanks

that will happen, yeah. when you bitstream it takes over the output - you cant bitstream and send regular audio over the same output at the same time. the answer is either use mpc to decode the audio first ( so that regular audio gets mixed in) or get a 2nd soundcard

thanks for advice...would there be any down side to having MPC decode 1st and not use spdif..i am interested in audio quality not cpu utilisation.

lose
loose

the appications lose speaker connectivity, maybe the wire is loose.
