Hi anjo

pulse audio is supported in nxp bsps located on

linux-imx - i.MX Linux kernel

For testing one can try steps described in sect.7.4 Pulseaudio input/output settings

attached Linux Guide.

Best regards
igor

Hi igorpadykov,

Thank you for the quick response. I was building with "DISTRO=fslc-framebuffer", which disables pulseaudio

if pulseaudio is installed in the rootfs, the pulseaudio input/output settings may need to be set. Pulse audio is only available for the X11 back-end Yocto Project rootfs.
