Created attachment 305378 [details] alsa-info output Actually the title is self descriptive. System: UM5302LA with BIOS 301. ACPI DSDT table contains correct _DSD configuration for SPKR (\_SB_.I2CA.SPKR._DSD). To prove it the dump of ACPI tables in windows with realtek drivers installed was compared against ACPI dump in Linux. To my surprise ASUS seems listen to customers and relatively new laptop with young BIOS have cs35L41 configuration out-of-the-box. UM5302LA comes with ALC294 with subsystem-id 1043:1a83, which is not covered in patch_realtek.c. Creating a bug to track changes required to get speakers working.
Actually, patching DSDT table is not required to fix that problem (I'm not expert, just can see _DSD section in DSDT disassembly output SPKR with pins configs). But open questions are: 1) Obtain correct firmware, which can not be found on cirrus git (at least now) 2) Apply the patch to enable quirks for subsystem-id 10431A83 On Windows I can't find firmware blobs for 10431A83: ``` find ./ | grep -i 10431A83 ./System32/DriverStore/FileRepository/dax3_ext_rtk.inf_amd64_1ef1d30092819137/DEV_0294_SUBSYS_10431A83_PCI_SUBSYS_1A831043.xml ``` So only DAX (Dolby extensions) are present. Suspected that in Windows realtek does use FW for another i2c based sub-id. After experimenting, I found that firmware for 104317f3 works with 10431A83 but it is required to create symlinks: ``` $ cd /lib/firmware/cirrus/ && \ for fw in $(find ./ -name '*104317f3*'); do newfw=$(echo $fw | sed 's/104317f3/10431a83/g'); echo echo "$fw -> $newfw"; cp $f $newfw; done ``` In addition, the patch should applied to patch_realtek.c (see attachment).
Created attachment 305379 [details] UM5302LA: cs35L41 quirks Proposed patch fixes initialization of CSC3551 on the UM5302LA laptop. Patching DSDT table is not required since ASUS did added _DSD entry. Nothing new introduced but reused work started by Stefan B. With the patch applied to 6.6.0 and obviously symlinks to 104317F3 FW, speakers works and to my surprise they sound is quite good and loud without distortion. Probably confirmation from cirrus team is needed on firmware.
