He once worked in full, with all drivers and other
if the drivers have the support Irbis TW89 yes, all at work. But if it is, for example, a sound card other than the rt5640 (eg rt5651 or es8316) is highly likely need to add support for Irbis TW89 to the driver in the kernel. To test a patched version of the kernel, which adds support for the tablet, you need to install the system, and install a new kernel on top of it.
vovikprofi, You can see what sound card is installed in this tablet? The properties of Realtek I2S ID 5640 or 5651? Or has a chip on Everest Semi? (Then most likely the ID will be 8316.)
