Hello,
The db845c is ported with Android 11 Automotive.
The kernel and android framework are from the master branch of android-common-kernel and aosp repository recently.
When I try to use “tinycap” to get sound from the mic on db845c:
tinycap /data/2.wav -D 0 -d 2 -r 48000 -t 5
The sound file can be acquied, but there’s no sound data found in it(data are all zero in binary format)
My config with “tinymix set” are listed below:
tinymix set ‘MultiMedia3 Mixer SLIMBUS_0_TX’ ‘1’
tinymix set ‘AIF1_CAP Mixer SLIM TX0’ ‘1’
tinymix set ‘CDC_IF TX0 MUX’ ‘DEC0’
tinymix set ‘ADC MUX0’ ‘DMIC’
tinymix set ‘DMIC MUX0’ ‘DMIC0’
tinymix set ‘DEC0 Volume’ ‘60’
Can anybody help or do you meet with such issue ?
Thank you so much.
