[pulseaudio-discuss] Unable to run pulseaudio on embedded platform

[Rinaldo Rex]

Hi,

I'm working on an embedded platform which runs automotive grade Linux. I'm
trying to use pulseaudio for a while now and it keeps failing. I've tried
modifying the configuration files and also by removing them to regenerate
the default values. Neither worked in an usable setup.

Please find the attached file as to what I've tried doing so far and please
guide me in proper direction.

Please let me know of any information you need to better understand my
problem.

Pulseaudio version: 6
ALSA version: 1.0.29

Thank you.
