RE: Re: [PATCH] ALSA: hda/realtek: Fix internal speakers for Legion Y9000X 2022 IAH7

[Stefan Binding]

Hi,

To clarify, was the log you attached here using:
 	{ "17AA386E", 2, EXTERNAL, { CS35L41_LEFT, CS35L41_RIGHT, 0,
0}, 0, 2, -1, 0, 0, 0 },
Or was it using your original value (index 1)?

The Speaker ID for this laptop should be index 2, if my ACPI for this
laptop is correct.
Both amps use the same GPIO for the interrupt line, thus the interrupt
is shared, and there is only a single interrupt line.
Disabling the interrupt on the second laptop is not a good idea, since
the interrupts are used to detect and recover from errors.

For further investigation, can you create a bugzilla ticket at the
below address and CC Cirrus Patches (patches@xxxxxxxxxxxxxxxxxxxxx) to
it.

https://bugzilla.kernel.org/

Can you also mention which distro you are using, as well which Kernel
you are using.
Also, can you please attach a dmesg of the error, as well as the
acpidump of your laptop.
($ acpidump > acpidump.out)
(You may need to install acpica-tools to do this)

Thanks,
Stefan
