and the mixer controls were shown with the headphones plugged in or without?
Iâve played around with alsamixerâŚand got it working. Removed the plug, enabled auto mute, disabled it and plugged in again. Now headphones are working and the internals are muted even alsa tells auto mute is off. Alsamixer Screenshot and amixcer -c 0 output, maybe you can puzzle that out.

Itâs a bit of a lotto with this auto switching, perhaps you were just lucky with 4.062. Pity I donât have a notebook or desktop with an HDA Intel soundcard, it is extremely difficult to debug this without it. It needs jack event handling, which was not implemented for this card. No promises, but I will see whether I can modify the âhandle_jack-headphone_eventâ script, when you are willing to test it.
Thank you very much.
Of course I am willing to test 
Best way to give something back to everyone 
In the meantime Iâve booted from a clean Volumio 4.067 install, that issue is there, too.
If you need anything or if youâd like me to test something, let me know.
Hi.
Volumio3.874 instaled on wyse 3040 x86. Wifi connected to router but not joinable. I can open webgui over wifi only when I conect LAN for 5 sec. I can disconnect LAN and connection is stable - internet radio is working. After reboot - same procedure is needed. Funny thing same procedure works when connecting volumio to my iphone hotspot - volumio need LAN for few sec. /diferent nettwork/ and its working via iphone hotspot. Any idea how to fix it?
Which version of Volumio are you running and donât say the latest?
latest⌠see my post 3.874 after update -tested. And btw static adrress for wifi - tested, hotspot off - tested, reset to factory - tested, dns - tested. same issue.
Yeah, totally missed the version in your post

Weâve seen issues with some adapters on V4, which is being fixed. However V3.xxx should be pretty stable.
