Internal Volume appears broken for me, just turned on pc and MC 23 and all I got was muffled playback. I looked at audio path while playing and discovered a -40 db for internal volume
I changed it from internal to anything else and all played fine.....
closed MC23 waited a bit opened MC22 and it plays fine with internal volume......not sure why.....all the setting are the same for MC22 and MC23
It's the same for 2 pc's with their own libraries with same music files from a external storage device. output via toslink to a 5.1 yamaha and 7.1 yamaha using W7. sound cards are same on both pc's. specs of pc's are quite similar but video cards are completely different tho I don't think any of this matters. Output is DGX (Asio)
EDIT: OK I did make a change yesterday to center speakers on both systems. I was junkin at the pawn shop and found 2 LG SH2 sound bars (powered). I am using them as the center speakers on both systems with modified wiring. They are phenomenal for centers as they have a remote and their volume can be adjusted instantly for tv and movie playback. But it still don't explain why MC22 internal volume is working.
