Hi at all, I’ve bought two raspiaudio mic+ to my project about an intercom SIP based.
I’ve used the first Mic+ to make the doorbell. This is configured with a Rpi 3B, Mic+ and the camera module. I’ve installed the raspbian (buster) lite and build the linphone SIP client and it works very well.
I’ve used the second Mic+ hat to make a video desk. This is configured with a Rpi 3B, Mic+ and official 7" Rpi touchscreen display. Also in this configuration I’ve build the linphone SIP client with desktop user interface because i need the h264 and g729 codec that the repository version don’t have. In this configuration I’ve much problems with the microphone because the volume is too low and it’s unusable.
As sayed in the Mic+ installation post, i’ve tried to change the raspberry board, to switch the raspiaudio boards, I’ve installed raspbian stretch, buster and sid, I’ve tried to use others sip client to test, like jami or also the linphone present in the repository but nothing to do. In one case I’ve uninstalled the pulse audio from raspbian buster and using jami the microphone has worked.
So, i think that could be some differences whith the management of the Mic+ board using the raspian desktop enviroments.
Can someone help me?
Thank you very much
