Re: PCI SSID and Codec SSID collision?

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



Here is my attempt. I hope it doesn't break with the DuetITL mode, I
chose to create a special case for it instead of otherwise because
there is an european version of the 14IRP8 with different codec SSID
(https://bugzilla.kernel.org/show_bug.cgi?id=208555#c778, 0x17aa38bf
vs 0x17aa38be).

This is my first time contributing with a commit and I'm not sure if I
did everything correctly so please let me know. I also don't know if I
should send it to a specific email with you as CC or something like
that.

Subject: [PATCH] ALSA: hda/realtek: Add special fixup for Lenovo 14IRP8

Lenovo Slim/Yoga Pro 9 14IRP8 requires a special fixup because there is
a collision of its PCI SSID (17aa:3802) with Lenovo Yoga DuetITL 2021
codec SSID.
