Last week an update arrived in PureOS with improvements for #Librem5 call audio. You should be more legible to your interlocutors during calls; also, the phone now automatically switches to external wired microphone once connected. The whole audio path went through a big overhaul, allowing for hardware volume control with zero-cross and reducing unnecessary amplification that could cause distortions.
Haven't seen people complaining about the changes so far - that's a good sign :)
@dos Has this been released to the public yet? Calls on my L5 has unfortunately regressed quite a bit since about a week or so. Incoming calls continue ringing and buzzing long after I answer a call, audio sometime routed through the speaker instead of handset and people complaining a lot about the call quality. #librem5
