Homebrew Sound Problems #30

Open under4mhz opened 1 year ago

under4mhz commented 1 year ago

I'm writing a game for ColecoVision, and I'm having issues with sound on the Phoenix. The background music isn't playing reliably. During the game the background music should be playing continuously, but it's mostly silent.

It works fine on the original ColecoVision hardware.

Any suggestions for what I could be doing wrong?

Working for me on Core 8... do your other titles play audio correctly? It really sounds like it's dropping out rather than not being emulated correctly.

It ended up being a problem with the specific unit. Possibly a problem with the HDMI cable. I had a friend try it on his unit and worked fine.

Thanks, Paul Chandler
