Just thought I would add more data to the thread.
I have the KS10s (VERY similar to the Phonak p90…) - My autosense works well - switches to music with music (takes about 5-10 seconds with my settings) as well as auto selecting car, loud, quiet, reverb etc etc. [I also have Telecoil and a custom music program as 2 other custom programs]
My audi changed the autosense music program to a more linear setting and decreased feedback “interference” as well as making a custom selectable Music program for my piano playing.
GENERALLY I leave the autosense in place UNLESS listening to the TV (The switching in and out of music auto-program is a pain with all the background music in modern TV shows) - then I choose the TV program which is essentially “speech in quiet”. With the new firmware the TV program has automatically populated the 4th ‘slot’ on my manual switch selectable programs so no need to always go back to the easy line app to select it.
I select the custom music program when playing the piano as we have worked harder to fine tune it and the autosense music program is better for the radio with mixed speech and music (rarely speech WITH background music unlike the TV)…
