[PATCH 2/2] ALSA: hda: Increase default bdl_pos_adj for Apollo Lake

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Apollo Lake seems to also suffer from IRQ timing issues. After being up for ~4
minutes, a Pentium N4200 system ends up falling back to workqueue-based IRQ
handling:

[  208.019906] snd_hda_intel 0000:00:0e.0: IRQ timing workaround is activated
for card #0. Suggest a bigger bdl_pos_adj.

Unfortunately, the Baytrail and Braswell workaround value of 32 samples isn't
enough to fix the issue here. Default to 64 samples.
