From d5a6cabf02210b896a60eee7c04c670ee9ba6dca Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 13 Jun 2018 12:43:10 +0200 Subject: ALSA: hda/realtek - Fix pop noise on Lenovo P50 & co Some Lenovo laptops, e.g. Lenovo P50, showed the pop noise at resume or runtime resume. It turned out to be reduced by applying alc_no_shutup() just like TPT440 quirk does. Since there are many Lenovo models showing the same behavior, put this workaround in ALC269_FIXUP_THINKPAD_ACPI entry so that it's applied commonly to all such Lenovo machines.

The entire point of a quirks system is to allow "programming by difference" from a given base case, which requires that merely defining a new quirk for some piece of hardware should not change the behavior of the driver for that hardware. In turn, this means that testing for QUIRK_NONE explicitly is a violation of that implicit contract. Change a test for QUIRK_NONE and QUIRK_ALIENWARE to default, and add a test for QUIRK_SBZ to disable the default behavior in that instance.

The code used a 32KHz rate when the comment says that it needs to use a 48KHz rate. And this has been the case since day one. On the Alienware M17x R4, the DMic used to have exceptionally quiet pickup and a lot of noise. Changing the data rate fixes both of these issues. Searching the kernel bug tracker for ca0132-related issues shows no mention of this being an issue for other hardware, and I have no other hardware to test with, so a quirk is used to limit the effect to just the M17x R4.

The root cause is that the HDMI codec on AMD GPU doesn't support CLKSTOP and EPSS, which are currently mandatory for powering down the HD-audio link at runtime suspend. Because the HD-audio link is still up, HD-audio controller driver blocks the transition to D3.

Among these 3 Lenovo machines, one of them has the same pin cfg as the machine with subid 0x17aa3138, so use the pin cfg table to apply fixup for them. The rest machines don't share the same pin cfg, so far use the subid to apply fixup for them.
