With a fresh installation of F32 on a Dell XPS One 2710, audio is muted by default on login, wake from sleep or user switch.
- If I type ‘alsaunmute’ the speakers start working.
- If I then plug in headphones, the speakers mute and the headphones work as you’d expect.
- But when I unplug the headphones, the speakers remain muted until I type ‘alsaunmute’ again.
In alsamixer, I see the ‘Headphones’ and Speaker channels.
- Plugging in headphones unmutes the Headphone channel and mutes Speaker
- Unplugging headphones unmutes the Speaker channel and mutes Headphones, but the speakers produce no sound despite volume being up
- After unplugging headphones, manually unmuting the Headphones channel without muting the Speaker channel makes the speakers produce audio (weird)
- alsaunmute seems to unmute both the Speaker and Headphone channels.
Can anyone think of a way I can make sure everything is unmuted at user login? And maybe persistently disable the auto-mute that happens when headphones are plugged in?
