Remove 'options snd_intel_dspcfg dsp_driver=1' and replace the second
options line as 'options snd-sof-intel-hda-common

[Touch-packages] [Bug 1845797]

2021-08-20 Thread perex
In other words: We don't have enough information to support this hw
(speakers). If vendor is not willing to add support to BIOS or give us
necessary information to add the proper initialization for the I2C
amplifiers to the driver, the only way is the reverse engineering (grab
the initialization HDA verbs in qemu or so). The another problem is that
the I2C master block in the Realtek codecs is not documented. Those
registers are hidden as the vendor specific coefficient registers.

For the mic volume - you may try to play with PGA / Dmic volume controls
in the native ALSA mixer application (like alsamixer). But it should
work with latest pulseaudio / UCM configuration.

It seems that there are some I2S amplifiers on the path to speakers and
the BIOS has only limited initialization. I will try to gather
information for C930 from Lenovo, too.
