UPDATE: I've opened a bug on ubuntu launchpad. See here: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/2048398
I bought a new Lenovo Yoga 7i - Intel i7 13700-H, with a fresh installation of the latest Ubuntu 23.04.
Everything works fine. The only problem is that I cannot change the volume of the laptop's speakers, i.e. the volume is always at maximum level. Moreover, I can mute the speakers.
Note that the Bluetooth works perfectly (I can instantly pair devices and control the volume).
I came across a similar question (Lenovo (yoga) slim 7 pro volume cannot be changed) but the solution does not work for me.
What can I do?
