Banana Pi M1 troubles

Post by skidoo »

Not directly related to MPD but maybe someone has useful ideas.

Hum: Banana Pi M1 with recent Armbian Buster is connected from internal audio to old late 70s Sony stereo (3 pin power connector). MPD from git uses ALSA output. When MPD plays no sound there is a quite loud hum. Hum goes away when MPD plays music and is again audible when playback stops. How to get rid of that hum?

Stuttering: when playing MP3 files (320 kBit/s) from internal sd card with libmpg123, no resampling every 10 to 30 seconds playback stutters. CPU usage according to top is well below 0.3. Maybe worn out sd card? Use input cache? How to get red of that damn stuttering?

Maybe usefull for someone. Installing Ambians firmware package for Banana Pi (and reboot) fixed choppy audio. Not able to get rid of hum and corrupted SD cards. My little adventure ended with a twelve year old fanless 1.3 GHz Celeron mainboard from scrapyard (Debian testing i386 - old board) and external USB DAC.
