Integrated speakers sound wrong on Surface Pro 3

cth451 · 2016-02-26 12:09:28

I tried playing the same audio file on Windows 10 and Archlinux. Sounds coming from integrated speakers from my Surface Pro 3 tablet seem to have the lower audio frequencies lost on Arch, which makes musics sound bad. However, with headphones the audio file just sounds the same in Arch as in Windows.

The problem can occur on both linux kernel in base repository and linux-surfacepro3 compiled from aur. Not sure whether it's a driver problem or incorrect pluseaudio/alsa configuration.

Feel free to request other things, any ideas are appreciated. Thanks!

Can you check whether Win 10 does some bass boosting (prob in audio settings)?

I don't think so. I've never changed or seen something like 'bass' or 'equalizer' settings in Windows 10.

Update:
There seems a few registry configurations here

HKLM/SOFTWARE/Microsoft/Audio/Hrtf

But somehow that's not arch related and hrtf is not related with bass boosting.
