  1. This issue is common to the NanoPi NEO Duo (H2 + Core) / NanoPi NEO Core (H3 Core) / NanoPi NEO Core2 (H5 Core).
  2. The same problem is still continuing. The first is the abnormal operation status log, and the second is the normal operation status log. The first one works with the Armbian Debian_stretch_next_4.14.78 firmware and the second one with the FrandelyARM firmware. Is there any way to improve this?

  3. I am useing "Armbian_5.59_Nanopineocore2_Debian_stretch_next_4.14.65.7z" image.
  4. The NanoPiDuo board is the same symptom. The following logs are left. root@nanopiduo:~# arecord -vv -f dat /dev/null Recording WAVE '/dev/null' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo Plug PCM: Hardware PCM card 0 'H3 Audio Codec' device 0 subdevice 0 Its setup is: stream : CAPTURE access : RW_INTERLEAVED format : S16_LE subformat : STD channels : 2 rate : 48000 exact rate : 48000 (48000/1) msbits : 16 buffer_size : 24000 period_size : 6000 period_time : 125000 tstamp_mode : NONE tstamp_type : MONOTONIC period_step : 1 avail_min : 6000 period_event : 0 start_threshold : 1 stop_threshold : 24000 silence_threshold: 0 silence_size : 0 boundary : 1572864000 appl_ptr : 0 hw_ptr : 0 arecord: pcm_read:2103: read error: Input/output error root@nanopiduo:~# aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Codec [H3 Audio Codec], device 0: CDC PCM Codec-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 root@nanopiduo:~#
  5. I tested with Armbian Stretch image on NanoPi-NEO-Core2. PJSIP VoIP Client. MIC input does not work. Additional USB sound cards work well. In FriendelyARM original firmware, MIC input works well. I hope that this issue will be resolved. Please help me.
