research [Info] Problems with analog-codec with BPi M1 A20 under kernel 5.3

Recommended Posts

BPi M1 A20 with kernel 5.3.7/5.3.8 there are some problems using the onboard-analog-audio :(
mpg123/espeak is freezing and cant write to the analog-audio via alsa.


A USB-Audio-dongle does work fine.


(also EOS devices like PCDuino A10 and Lime A10 have audio sync-problems with kernel 5.3 (but do work)  - but its "OK" they are EOS)


The BPi M1 A20 has no problem with the analog-codec while using kernel 4.19.81-sunxi

analog-codec seems to be always active, because if enabled as overlay or not the analog-soundcard s shown:

aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sun4icodec [sun4i-codec], device 0: CDC PCM Codec-0 [CDC PCM Codec-0]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
