Here are some updated notes on what plays / does not for me using MC V141 / Vista 32-Bit SP1 / Gigabyte HD4550 / Cat 9.2 / Realtek R218 Drivers / 5.1 Ch set in Audio Cntl Pnl --> using the various B.Britten: Simple Symphony tracks at
http://www.2l.no/hires/index.html - I've not played with any WASAPI settings at all.
Surround 5.1 DTS 24BIT/44.1kHz - Output = Fine, 5.1DTS Bitstream is sent to the receiver
- Pausing = Issues
a) Pressing "Play" causes the Receiver to flash on/off that it is getting a DTS Stream (eg the Stutter) but it is paused. Press "Play" again and it starts playing fine.
b) Pressing "Pause" seems to force the Audio out stream to 2CH PCM & from then on you don't hear anyting and can not resume playback. You have to press "Stop" and start again.
Surround 5.1 FLAC 24BIT/48kHz - Output = Fine, 5.1 PCM is sent to the receiver
- Pausing = Issues, I'm getting the usual stutter, however as reported above it will also occasionally also freese when presssing "pause" (you hear nothing, the song does not advance) but you can stop and restart the track
Stereo FLAC 24BIT/48kHz & Stereo FLAC 24BIT/96kHz & Stereo WAV 24BIT/96kHz - Output = Fine, 2.0 PCM is sent to the receiver
- Pausing = Issues, same probs as above.
Surround 5.1 FLAC 24BIT/96kHz - would not play - MC13 error message "Playback could not be stated on the output "Windows Audio Session API (WASAPI) using the format 96000Hz, 24bits, 6ch" - Note: I've not played with any buffer settings and others have reported this one plays.
Stereo FLAC 24BIT/192kHz - Output = Wrong CH Configuration as 5.1 PCM is sent to the receiver
- Pausing = Issues, same probs as above.
Surround 5.1 WAV 24BIT/48kHz - will not play - messages in MC13 is "analyse files --> there is nothing to play"
MP3 / WA Lossless- Output = Fine, 2.0 PCM is sent to the receiver
- Pausing = Issues, same probs as above.
Summary: There is still the issue with "Pause" that causes the stutter or even stalls the playback of the track with all audio media types. The dynamic allocation of Channel Mapping is correct for all but one file type. MC's WASAPI Implemenation does not reset the Audio output to the default set in the control panel (eg mine is 5.1) but sets it at 2.0 CH.
