11028	Audio output remains Dolby Digital when channels shift from 5.1ch to 2ch	rparrish@…	JYA	"Mythfrontend is configured with speaker count set to 5.1, AC-3 passthrough enabled, and upmixing disabled.

When watching a recording which begins with DD Stereo audio, output is PCM Stereo as expected. If the audio track changes to DD5.1, output changes to DD5.1 -- also as expected. But when the audio track changes back to DD Stereo, the output switches to DD Stereo instead of PCM Stereo. I have verified this behavior using the indicators on my audio/video receiver.

I have hosted a test clip which can be used to demonstrate this behavior at this link: http://sdrv.ms/SYrb8a (Link points to file on my Microsoft Sky Drive account)

I am using Mythbuntu's 0.25-fixes repo on Ubuntu Lucid.
