However, where is your dmesg and/or ALSA log when the regression occurs? What is the playback test file? FYI, 9f656705c5faa1 ("ALSA: pcm: rewrite snd_pcm_playback_silence()") is originated as [1/2] of patch series that pokes around the auto-silencer. The other patch ([2/2]) got NAKed since autofilling buffer should have been done in alsa-lib (still to be discussed) [1]. Anyway, I'm adding this to regzbot: #regzbot ^introduced 9f656705c5faa1 #regzbot title Much echoing when playing sound files on Intel Alder Lake PCH-P Audio Controller Thanks.

[PATCH] ACP6x audio: Add board quirk for ASUSTeK COMPUTER INC. M3402RA
by István Váradi 01 May '23

01 May '23

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

Question regarding ALSA modules parameters
by Ivan Orlov 01 May '23

01 May '23

Hello! I have a question about the typical ALSA driver parameters, and maybe someone can answer me. Why it is necessary for ALSA module to have "index", "id" and "enable" parameters? They are mentioned as required in the "Writing an ALSA driver" and "Advanced Linux Sound Architecture - Driver Configuration guide" articles and used in many ALSA drivers, but for what purpose? Kind regards, Ivan Orlov.
