[alsa-devel] [PATCH] ALSA: hda - Add two more machines to the power_save_blacklist

[Jaroslav Kysela]

Dne 08. 04. 19 v 3:35 Hui Wang napsal(a):
> Recently we set CONFIG_SND_HDA_POWER_SAVE_DEFAULT to 1 when
> configuring the kernel, then two machines were reported to have noise
> after installing the new kernel. Put them in the blacklist, the
> noise disappears.

Please, place the new entries sorted using the PCI IDs...
