[Acer Predator g9-592] Sound playing only via subwoofer


my problem is not Endeavour specific, as I also face it with pure Arch. The topic basically says it all - my laptop is Acer Predator G9-592 which comes with built in 2.1 speaker system, and all sound is coming out of subwoofer which in tests is recognized as ‘left front’.

I played with pavucontrol, alsamixer, but sound configuration isn’t the thing that I’m good at. I looked for soultions @ Arch wiki and forums, but didn’t found any good ones.

Could you guys help me to work it out?

Have you tried anything like this?

Nice one, it actually works. The only thing is that I couldn’t test it on the fly, I had to “Install boot override” and then test. Thanks!

So this worked then? Wow … that’s cool. :blush: I read somewhere UEFI uses the esc key to display grub? Not sure though.

Yup that works just fine (cannot test whether the sub is playing or not - my kids are sleeping).
Don’t know how I missed that solution, perhaps not enough digging, maybe DuckDuck showed me some inacurate results…

Anyway, well done.

So you got speakers working but not sure on whether the sub is also working i take it? Sometimes these solutions are hard to find. I’m used to skimming through stuff as there is so much garbage on the internet. I hope the sub works too.

Actually I just ran `speaker-test’ utlility which allows me to silently check wheter speakers are playing corrently, and something is wrong, I think front left is playing together with subwofer. I will play with setting maybe tomorrow and post solution if I’ll fix this. I suppose that its just about assigning correct pins to channels.

@patryk I see that there is some info here on sound problems that has been added in case you are still having issues.
