LG Gram Style 14 Laptop To See Working Speaker Support With Linux 7.0
For the Intel-powered LG Gram Style 14 laptop one of the Linux support caveats is the internal speakers not working properly under Linux, but with a patch expected for the upcoming Linux 6.20~7.0 kernel cycle it will finally fix the laptop speaker support for one of the laptop models in this series.
It doesn't take much searching to find Linux users reporting broken speaker support for the LG Gram Style 14 laptop. An issue going on for years while some users have luck with applying user-space HDA verbs to enable speaker support and apparently some not having the same luck.
Queued up this past week within the Linux sound subsystem's "for-next" Git branch is a patch for finally fixing the LG Gram Style 14 speakers. The patch notes:
The LG 14Z90RS-G.AD77F model in question is for their Intel Core "Alder Lake" generation laptop. We'll see in time if this ends up being expanded for the other LG Gram Style 14 laptop models.
There are already sound quirks in place for other issues on LG Gram 16 and LG Gram 17 laptops too. It would seem LG Gram laptops have a tendency for their sound support to be quite quirky under Linux, as an important factor if considering one of these laptops for Linux use.

"The LG Gram Style 14 (14Z90RS-G.AD77F, SSID 1854:0490) with Realtek ALC298 shows normal routing and volume changes, but internal speakers stay silent unless a userland HDA-verb workaround is applied.
Add a dedicated quirk for the LG Gram Style 14 that programs the codec coefficient sequence used by the known workaround and enables the speaker amps only during playback."
