[ALSA] intel8x0 - fix capture for M1563
Modules: Intel8x0 driver 1.In intel8x0_measure_ac97_clock routine, when stop DMA, there is not stop DMA corectly, but start another PCM In2 DMA engine. 2.In do_ali_reset routine, there is only need to enable PCM IN and PCM OUT. Signed-off-by: Jaroslav Kysela <perex@suse.cz>
