0x64 "RequestApplicationLaunch" error #18

Closed arturopolanco closed 4 years ago

arturopolanco commented 4 years ago

Hi all,

I'm unable to play anything, the speaker test fails with a _Write error: -5,Input/output error, xrun_recovery failed: -5,Input/output error__

I'm using some old Libratone speakers and it's the same for both. I only see an error for the command 0x64 "RequestApplicationLaunch" but is that causing the issue? It's just an application launch and it only appears once.

I would really appreciate some hints here :) Thanks a lot!

hi @arturopolanco I just pushed a change to handle this message. It's possible the speaker was waiting for a response.

It's also possible it starts streaming only when dispremote.RetPlayStatus returns Playing status: https://github.com/oandrew/ipod/blob/master/lingo-dispremote/handler.go#L110

Hey @oandrew ,

Thanks a lot. The 0x64 answer didn't do the trick but I don't see any errors. Then I set the Playing status to 1 and was able to successfully run the speaker-test. Now I'll continue with a snapcast to stream audio to it.

Thanks a lot, once again. 🥇
