Pre-installed Android Pie
Please describe your issue below:
I’m using VIM3L with pre-installed Android.
I’m suffering from a usb microphone
I connected a usb soundcard.(SiliconLabs evaluation board).
VIM3L recognize the soundcard and its microphone.
The speaker output works fine.
But recording from microphone gives no sound.
Google Transcribe App can see the microphone of the soundcard but does not produce any text.
With Galaxy Tab and Lenovo Tablet Google Transcribe App works fine with the microphone.
Post a console log of your issue below:
Well, It was USB sound card that produced the problem.
I switched to another cheap usbsound card and finally I got voices from the usb microphone
Any Class 1 USB sound card should work with VIM3 Android.
@lightvil For these two USB sound cards, execute the following commands to compare and see the difference:
# cat /proc/asound/cards
