Re: [Freeswitch-users] mod_portaudio on Raspberry Pi does not find connected audio devices

30 Jun 2020

      Hi,

Update: I have also installed successfully the original portaudio 
according to instructions under 
https://app.assembla.com/wiki/show/portaudio/Platforms_RaspberryPi

    --> the version is equal to the version that I see through
    mod_portaudio in fs_cli
    --> portaudio/bin/pa_devs find several "devices", but from among my
    physical devces connected through aux, BT and USB, it can only find
    the USB device
    --> pa rescan in fs_cli, however, continues to report that no
    devices were found, not even the USB one...

I would appreciate very much any help.

Thanks and KR,

Hi,
here is a short summary of my configuration and issue:
1. Pi-4 with Raspbian buster and latest related FreeSwitch
    distribution, apt-upgraded and updated on last Friday
 2. aplay is working both with the audio jack and with bluetooth
    (although not simultaneously: as soon as I have a bluetooth audio
    connection, the audio jack stops to work, and I cannot switch back
    to it with "amixer cset numid=3 1", but aplay can continue to use
    the bluetooth connection again after I issue "amixer cset numid=3
    65536")
 3. It seems that I do not have any permission issues as both of the
    users pi and freeswitch are in the audio group, which has rw
    access to the related devices under /dev/snd
 4. I have already installed alsaoss, libasound2 and libasound2-dev
 5. The output of "pa rescan" in fs_cli is the following:

Any clue, what could be wrong on my side?
Thanks!
