Hello,
I am running Pulseaudio version 14.2 on a iMX8 (64-bit) NXP Hardknott Yocto OS. My application interacts with PulseAudio via the API. It connects to the sinks asynchronously with the callbacks and streams data using the pa_simple_write function. The audio produced is static-filled. This same application runs with no problems on iMX6(32-bit architecture) Technexion Hardknott Yocto OS using the same PA configurations.
Timer based scheduling is turned off by default in "/etc/pulse/default.pa" with "load-module module-udev-detect tsched=0"
Also, rendering audio directly to ALSA, while by-passing Pulseaudio produces static free audio. We suspect the problem is with the Pulseaudio to ALSA communication.
Are there possible differences in how Pulseaudio works in 64-bit architecture compared to 32-bit architecture?
Any suggestions on how to further troubleshoot this will be much appreciated.
Thank you
