Source: linux Severity: wishlist Dear kernel maintainers,
I have a Legion Pro 7 laptop, which I made my company buy because it has 16 cores, so I can build stuff faster. I love the hardware, but it produces no sound: sound board is supported, but it looks like the current Debian kernel doesn't have its speaker driver enabled. It took me a lot of research to find this patch: https://e2e.ti.com/support/audio-group/audio/f/audio-forum/1208376/tas2781-tas2781s-linux-drivers-for-lenovo-laptops/4603230?tisearch=e2e-sitesearch&keymatch=tas2781 which I tried applying on top of the Bookworm backport kernel, to find out that it was already there. I then understood that the missing bits was probably the kernel configuration. As much as I understand, we need: CONFIG_SND_HDA_SCODEC_TAS2781_I2C=y in debian/config/config approx line 7928, near the line CONFIG_SND_HDA_SCODEC_CS35L41_I2C=m I don't think this can be loaded as a module, but I may be wrong. Please let me know if I'm right, or if other parts are missing to make sound work on my laptop. Cheers, Thomas Goirand (zigo)
