Dear Mr. Yang and ALSA contributors,

Currently, I'm trying to fix ALC285 for HP Envy x360 13-ar0107au convertible laptop on Linux v6.7.6 kernel. It has several problems including B&O soundbar speakers won't work and volume too low even though it's 100%. For now, the B&O soundbar is working. However, I'm still struggling to fix the low volume problem. The draft patch is attached to this mail. If you don't mind, please let me know the information about the correct coefficients, so I can help you fix the problem and test it on my device. Thank you for your attention.

Sincerely,

Eric
