audio doesn't work after putting system to sleep

[dwiel]

When I put my computer to sleep, talon no longer recognizes popping noises. The only reliable way I can get it to work again is restarting talon. Is anything I can do to help debug and figure out what is going on? I put a print statement as the first line of a pop handler, and it isn't getting run.

is this new? which talon version are you on?

[dwiel]

Pretty sure its been this way since I started, but I've only got everything stable enough in the past few days to narrow down the cause.

v0.0.8.29-1482-gcb4e401 (1482)

does it start working again if you manually switch mics in the talon menu?

[dwiel]

Yeah that does the trick. It is infact still working, its just using the wrong mic. The menu bar says it is using "System Default (Sennheiser DECT)" but it isn't. it is using the builtin mic.

Can you try 1488?

[dwiel]

same issue with 1488

[lunixbochs]

Does it go away with 1488 if you manually change the mic before sleeping?

I should probably stop / restart all audio streams on sleep / wake to fix this

Need two things for this:

1. Sleep/wake events on each OS.
   • macOS
   • Linux
   • Windows
2. Wire these events up to re-initialize the audio system.

Linux: we need the d-bus signal PrepareForSleep. Some examples here: https://serverfault.com/questions/573379/system-suspend-dbus-upower-signals-are-not-seen

Windows: we need to listen to WM_POWERBROADCAST. Example here: https://forum.qt.io/topic/69485/do-an-operation-when-computer-goes-to-sleep
