I see this was an issue awhile back. Well I now have this issue. Tried all the driver routines. Does it with mapper, asioforall, audiobox asio, waves classic. Also the buffer changes works a little for the asios but makes the meters on audio track fx out of synce. I believe behind it looks like. Already sent a report to tech. Anyone here got a clue let me know. I'm starting to think I need to clean my ears out. : )
I don't know why the audio doesn't come thru but if you look at the master meter you can see it freeze. This is when audio glitches or stops. Video looks fine.
Also did the latency test with a program called latencymon and it passed 100% with no driver issues or latency.
