MSI Modern 16S AI+ G3MG (PTL): ghost rt722 on link 3, please add to ghost_realtek DMI quirk #6033
Description
Good afternoon,
The MSI Modern 16S AI+ G3MG declares a Realtek RT722 on SoundWire link 3 in ACPI
that is not physically present, next to the real RT721. Same "ghost Realtek" case
as #5857, and the same -EEXIST failure. Could this model be added to the
ghost_realtek quirk in drivers/soundwire/dmi-quirks.c
(commit 4dab2b9, "soundwire: dmi-quirks: Disable ghost Realtek devices")?
DMI:
sys_vendor: Micro-Star International Co., Ltd.
product_name: Modern 16S AI+ G3MG
board_name: MS-26U2
BIOS: E14U2IMS.106, latest available from MSI
System: openSUSE Tumbleweed, kernel 7.3.3-1-default
Audio PCI: 0000:00:1f.3 [8086:e428]
SoundWire devices:
sdw:0:3:025d:0721:01 rt721 Attached
sdw:0:3:025d:0722:01 rt722 Unattached (not physically present)
dmesg:
sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:1f.3/sof_sdw/SDW3-Playback-SimpleJack'
kobject: kobject_add_internal failed for SDW3-Playback-SimpleJack with -EEXIST
sof_sdw sof_sdw: probe with driver sof_sdw failed with error -12
Result: no sound card at all. Blacklisting snd_soc_rt722_sdca only leads to
"snd_soc_register_card failed -517" (deferred probe). Also reproduced on
Zorin OS 18 with kernel 7.0.0-38.
Happy to test a patch or provide acpidump / alsa-info.
Many thanks and kind regards

@KE1701 Can you test #6034?

Good morning Bard Liao,
Thank you very much and tested #6034 on openSUSE Tumbleweed, kernel 7.3.3-1-default (rebuilt
soundwire-intel with the patch applied, Secure Boot disabled).
Result: the ghost rt722 is gone, only sdw:0:3:025d:0721:01 remains in
/sys/bus/soundwire/devices/, and the card registers. Speaker, headphones,
internal SoundWire microphones, headset microphone and HDMI outputs all work.
Thanks a lot for the quick fix!
Kind regards,
Kay
