[Solved] Audio output switching with toggle switch

The script looks fine - I don't see any problems with it. How are you testing if it works ?

All of them use the os.system command. That's why I'm thinking it's a retropie change to how audio is handled.

why do you not test via CLI to toogle sound. Just enter the command sudo amixer cset numid=3 2 and see what is happening? As @mitu told there seems no error in the script.

PS: Are you in DVI mode? Maybe you can force HDMI sound by adding hdmi_drive=2 to your /boot/config.txt

[oldspicy]

@cyperghost tried that, still isnt working. The amixer code just isnt activating for some reason.

[mitu]

@oldspicy Did you check the volume with alsamixer when switching between audio outputs ?

[oldspicy]

@mitu both in game and from the command line

[oldspicy]

@mitu I haven't because there is audio out both, but I'll try that in a bit

[oldspicy]

@cyperghost I can force one or the other, but the point is to toggle. Sometimes using hdmi, sometimes using the internal speaker

@oldspicy I quickly tried on my build ... the commands amixer cset numid=3 2 works. But I'm still on a Jessie build! Maybe @mitu can test?

[oldspicy]

@cyperghost @mitu Okay, so I found two more problems. Bluetooth controllers are flaky, and the shutdown script won't work if the screensaver is active. The screensaver holds it and shutdown wont happen.

I still have a build I imaged from jessie when everything was working. It's a bit old and I'll have to rebuild some things, but it might be easier. I haven't noticed a big reason to update. I just did because the files got corrupted and I figured it was a good time to update everything.

But thanks for trying!

@oldspicy Can't say I've seen the shutdown command being unable to actually shutdown/restart unless there was an I/O kernel operation stuck somewhere.

@mitu I'm going to try wiping and a fresh install one more time before I give up, maybe something was corrupted that I couldn't find.

[oldspicy]

@cyperghost @mitu Okay, so a clean install fixed everything. I'm not sure what happened the first time, but now the audio switching works, along with the power and bluetooth. Something must have went wrong on the first install. Thanks for taking the time to help me troubleshoot though!
