ALSA: ali5451: Support PCM sync_stop (5110bc70) · Commits · 戴 / test

The driver invokes snd_pcm_period_elapsed() simply from the interrupt handler. Set card->sync_irq for enabling the missing sync_stop PCM operation, as well as removing the superfluous synchronize_irq() call. Link: https://lore.kernel.org/r/20191210063454.31603-3-tiwai@suse.de Signed-off-by:
