ALSA: hda - Fix bdl_pos_adj value for ATI SB chipsets (5c0d7bc1) · Commits · 戴 / test

ATI SB controllers seem to report the DMA ahead in the amount of FIFO. Thus bdl_pos_adj should be 32 for them as default. Also, the default value is set to -1, which means to make the driver to choose the appropriate value. Signed-off-by:
