This minor annoyance is specific to my hardware, that the headphone jack won’t work without ac adapter on this laptop (will work under a special case)*
*It works if something is playing and I disconnect it, and don’t stop playback at all without the adapter, and plug it back in.
Basically it stops when no ac adapter + nothing playing, then it stops working unless I do the following:
Suspend the laptop, Plug in the ac adapter, switch it on, wait for ~5 seconds, plug in the jack
Also popping sounds can be heard on connecting the jack.
I want to figure out if I can work around this by disabling some power saving setting, or do I need to get it replaced.
There are no settings for sound card power management to be found in yast sound module.
Interesting. I would not have guessed this as a solution. I have read of “SOUND_POWER_SAVE_ON_BAT=0” being used as a fix to address a problem where Speakers pop when starting audio system
One possible side effect of this may be that on a laptop with battery this may drain the battery a bit faster.
Yes, although I’m aware of TLP and what a useful utility it is, I didn’t realise it is installed by default in Tumbleweed. I know some users manually install it in other portable desktop environments though.
