My hypothesis is that the drivers are just not optimized but I am not a computer engineer so my theory is worth very little. However, the free FXSound software completely changes how the speakers sound in quality and loudness. Its a significant improvement! I tweaked the Volume Boost setting like this and it sounds as good or better than any laptop, tablet I have used.
Windows seems like it addresses them like a different set of speakers; is it a different driver, or emulating drivers? I don’t know. But until FrameWork updates the drivers for these speakers or the DAC they changed to**, try the FXsound software. It seems to improve headphone and bluetooth sound quality as well.
** I have NO idea if the change from Realtek ALC295 to the Tempo 92HD95B mentioned in this article has anything to do with the weak speaker performance or not, its just my theory as to why the speakers are driven so weakly.
