Rather randomly a commit that fixes speakerphone on the Pinephone also fixes that for Nexus 6P - Note that the volume is very low, but thats just a tweak for the mixer-config, and I can take a look soonish. But the actual audio routing was resisting to work, until today.
Note that like all other fixes you can receive it immediately only if you are on the devel channel.
as you note, the volume -and the speakerphone - is very low on the (my) Google Nexus 6P. Could you explain us how to get it more efficient ?
@pe2a Humm I actually never found time to look into this. I put it back on my list... There is nothing you can do out of boy though.
So the best for me is... "wait and see" : sometimes, waiting is urgent !
