Not sure I have anything to add here but I was starting a new transcription of apiece, which I do by taking an mp3, creating a video, and importing into Dorico. Not had a problem previously, but with this new one, sure enough, no sound with the video. Opened it up with D2 and it was ok. So first tried playing within the mixer with no luck including the comment on this thread - didn’t seem to help at all. Next attempt, switched sample rate from 44.1 to 48 and nothing. Then deleted the detached and reattached. Now it plays. Out of curiosity I then switched it back to 44.1 but alas, it changed the pitch and tempo to not be that of the original. Not sure what all this really means - didn’t have the issue in D2. Anyway, I’m not “blocked” now as I have a project I can work with normally - but it is oddly different than D2. Haven’t tried opening old transcription projects to see how the 48 setting is going to affect those…but those are done anyway!
Hmm, just now opened up the advanced config options for ASIO4ALL and noticed that “Always resample 44.1kHz <-> 48kHz” checkbox is not checked. Wonder if that’s the issue? Nope. I set the check box, changed preferences back to 44.1, no change. Then left it at 44.1 detached and reattached video. No sound at all. Reset to 44. Still no sound. Then detached and reattached video. Working again, with same pitch change if I then go back to 44.1
So… lesson learned for now…set preferences to 48 BEFORE loading in the video…and audio will play correctly. Don’t change back to 44.1 at this point as it changes the pitch of playback. So I have a working scenario for my project at least.
Hope someone finds this helpful.
