And the system volumn control only affect the upfacing speakers nor the
downfacing bass speakers.

workaround-for-lenovo-thinkbook-16p-gen4-IRH-sound-issue.md

Please do check the kernel version before applying.

1. Not verified, use at your own risk plz.
2. Known issue: volumn actually adjusting the freq.
3. zh-CN blog: https://levihuayuzhang.github.io/blog/2023/think-book-16p-sound-fix/
4. My alsa-info: http://alsa-project.org/db/?f=1ad9f2709886f0ec5d2d87d5d8e59a0ac05384be

This issue should be fixed by v6.9-rc5 or later. If you still encounter bugs, please feel free to discuss at here or report it to Kernel Bugzilla.

Hi Huayu, I have the same issue on my Thinkbook 16P 2024. After attempting the patch, my laptop no longer has kernel errors, but it seems that only the upper low-frequency speaker is working, while the lower high-frequency speaker is not working. Do you have any information or help regarding this?

看到兄弟的提交了。估计会排期解决的。加油。（有用Gen5型号的朋友可以去跟帖汇报哈）（可以关注linux sound邮件组，Cirrus的几位佬）

然后估计CS35L41的驱动已经写好了。兄弟可以考虑把没打patch的kernel报错给发一下，alsa-info好像看不到amp型号，还有acpidump的输出可以重定向为文本，发给Bugzilla。（有可能是其他型号的amp，新型号或其他厂家的（比如德州仪器之类的））。

然后估计CS35L41的驱动已经写好了。兄弟可以考虑把没打patch的kernel报错给发一下，alsa-info好像看不到amp型号，还有acpidump的输出可以重定向为文本，发给Bugzilla。（有可能是其他型号的amp，新型号或其他厂家的（比如德州仪器之类的））。

我刚刚跟新了bug的描述。希望能被大佬看到。在我电脑上6.8的内核，低频的Speaker是有声音的不过超级小，高频的Speaker不work

Hi Huayu, I have the same issue on my Thinkbook 16P 2024. After attempting the patch, my laptop no longer has kernel errors, but it seems that only the upper low-frequency speaker is working, while the lower high-frequency speaker is not working. Do you have any information or help regarding this?

看到兄弟的提交了。估计会排期解决的。加油。（有用Gen5型号的朋友可以去跟帖汇报哈）（可以关注linux sound邮件组，Cirrus的几位佬）

那应该就是cs35l41了。估计是配置问题。我当时就是上边音量还可以，并且可以调整大小。下面也有声音，但小，且无法和上方一起协同调整音量。这种情况就是解码器可以解码，amp也在工作，但估计之间的连接配置没写对。

我当时是试了几个不同的配置，其中一个刚好可以用。有几个配置在sound/pci/hda/patch_realtek.c里是写好的（可以ctrl+f搜搜看）。不过也可以在邮件组问问Stefan，之前都是这位大佬在对接这个芯片的相关事项。（如果确实是配置的问题，之前 Stefan说要去找Realtek的人问，或者自己尝试用已有的配置or自己写😂）。祝顺利。
