You seem to be using some ASoC driver, so that's where I would look first. Aplay and PulseAudio are sometimes using the driver in slightly different ways, so even if aplay works that is not a guarantee that the fault is in PulseAudio. > efault, new rate is 48000 > I: [p[

propagate up and cause follow-up errors, but that's likely not the root cause here. > D: [pulseaudio] module-suspend-on-idle.c: Sink alsa_output.default > becomes busy. > I: [pulseaudio] resampler.c:
