ALSA: emu10k1: Support PCM sync_stop (66471aa7) · 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. Link: https://lore.kernel.org/r/20191210063454.31603-17-tiwai@suse.de Signed-off-by:
