Hi,
I had Telefunken (Starkey Evolv AI 1600) and Starkey Genesis AI RIC. Both, after exactly 45 minutes of streaming mp3 audio from a Google Pixel 6 (Android 13), started to stutter.
Restarting the audio files helps, for exactly 45 minutes again.
Anyone ?
Hopefully. 
I read about (incompatible) audicodecs and android 12 problems here and there, but nothing about stuttering. Maybe somekind of buffering issue ?
Unfortunately I have not come across this issue before, it’s really unusual the timing?
Can you try another phone to confirm, is it just music files or what about streaming a movie, same thing? Are the MP3 files streamed from online or from internal hard drive.
