Dear Linux Kernel Developers, I hope this email finds you well. I am writing to submit a patch for the ACP6x audio driver in the Linux kernel that adds a board quirk for the ASUSTeK COMPUTER INC. M3402RA. After experiencing issues with this board on my Linux system, I researched the issue and found that adding the following code snippet to the file sound/soc/amd/yc/acp6x-mach.c should resolve the issue: { .driver_data = &acp6x_card, .matches = { DMI_MATCH(DMI_BOARD_VENDOR, "ASUSTeK COMPUTER INC."), DMI_MATCH(DMI_PRODUCT_NAME, "M3402RA") } } As someone with no experience with the Linux kernel, I am submitting this patch in the hopes that it will be beneficial to a larger number of users. I have tested this patch on my own system and can confirm that it resolves the issue. Please let me know if you have any questions or require any additional information. Thank you for your hard work and dedication to improving the Linux kernel. Best regards, Steve Váradi
