Sidenote: the way that I implemented this makes it so that it doesn't require package rebuilds.

This is currently a draft due to speakersafetyd/unknown if speakers have hardware limiting.

Cool, will test when I have time, thanks.

How well is it working for you? Jos reported that "it will sound very distorted".

Yeah, we should probably wait for a while before merging this, see if any work comes along on the speakersafetyd front.

But if not, and otherwise it's working without issues for us, we could consider merging it behind an op-in enable flag along with a stern warning in the README about people being responsible for breaking their own speakers.

It is definitely distorted, even to my not-audiophile ears.

I guess we could put it behind a config flag.

Also, I don't have my good recording equipment on me ATM so I can't replay a sample for you.

Huh? https://psref.lenovo.com/Detail/Yoga_Slim_7_14Q8X9?M=83ED0001US

4 stereo speakers, 2W x2 (woofers), 2W x2 (tweeters), optimized with Dolby Atmos®, Smart Amplifier (AMP)

Does that mean it's already protected by hardware? @kuruczgy

I have no idea... you might wanna ask about this in #aarch64-laptops, there are some more knowledgeable people there.

But there is already one person with a Yoga Slim 7x there who seems to have broken their speakers, so until we have strong evidence that there is hardware protection and that person is having some other issue, I will assume there isn't.

Also wanted to ask @powpingdone, what nix formatter are you using? I am using nixpkgs-fmt, but now I see that it's deprecated... I guess we should switch over to nixfmt (nixfmt-rfc-style in nixpkgs), that seems like the most official one?

@kuruczgy

What formatter?

I have heard someone broke their speakers already.

Then what's the best way to contact the #aarch64-laptops IRC without exposing my IP? I've heard some mumbling about matrix but i'm not sure what to do or where to go for that.

I mean you can use an IRC bouncer or a VPN or Tor.

Here is the Matrix link: https://matrix.to/#/#_oftc_#aarch64-laptops:matrix.org
Though Matrix isn't a very well engineered system either, and I have no idea if it's any better on the privacy front than IRC...

Maybe this will come in handy? hogliux/yoga7x-firmware@72b9daf

AFAIU that's the file being compiled in audioreach-topology.nix
