Soun d Architecture': Could not get/set settings from/on resource.
[gstalsasink.c(666 ): set_hwparams (): /pipeline0/alsasink1:
This is because au88x0 driver require the period_size to be power of two
snd_pcm_hw_constraint_integer(runtime,
SNDRV_PCM_HW_PARAM_PERIODS)
snd_pcm_hw_constraint_pow2(runtime, 0,
SNDRV_PCM_HW_PARAM_PERIOD_BYTES)
This is no enough for alsa-lib to refine the hardware parameters (buffer_size,
period_size ,period , buffer_time, period_time ) when application (e.g.
gstreamer, wine) call snd_pcm_hw_params_set_buffer_time_near() or
snd_pcm_hw_params_set_period_time_near()
possible fix may be adding another constraint for buffer_bytes to help alsa-lib
to refine that hardware parameters
