From c563f473ac31c182d93f4c6ec8eb0ce199439978 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 6 Aug 2014 14:27:42 +0200 Subject: [PATCH] ALSA: hda - Fix probing and stuttering on CMI8888 HD-audio controller ASUS Phoebus with CMI8888 HD-audio chip (PCI id 13f6:5011) doesn't work with HD-audio driver as is because of some weird nature. For making DMA properly working, we need to disable MSI. The position report buffer doesn't work, thus we need to force reading LPIB instead. And yet, the codec CORB/RIRB communication gives errors unless we disable the snooping (caching). In this patch, all these workarounds are added as a quirk for the device. The HD-audio *codec* chip needs yet another workaround, but it'll be provided in the succeeding patch.
