Finally after much effort got my soundcard to work nicely.
Having compiled a new kernel which picks-up almost all the hardware on HP G2 X2 201 2-in-1 tablet with 4g ram and 64GB storage.
I finally found what works to get this soundcard to produce clear sound, at least on Fatdog64-800.
This works with libapulse, no need for pulseaudio and pavucontrol.Needs correct UCM files and intel firmware.
Download the attached asound.state config file and copy it to /etc/asound.state. Blacklist module 'blacklist snd_hdmi_lpe_audio', this might not be necessary. Set the defualt soundcard '1'.
Reboot and play music, I used vlc>audio device>direct hardware.

I have found that I have to blacklist 5 sound modules and modprobe 3 of them after X starts.

Microsoft Surface 3
I have no sound in Bionic Puppy 8.0 x64 on my Microsoft Surface 3 (reported in http://murga-linux.com/puppy/viewtopic. ... 01#1049101), which has the Intel Atom x7-Z8700 Processor - I believe that too is Cherrytrail. I will have a go at downloading your asound.state config file and blacklisting module snd_hdmi_lpe_audio to see if that resolves the problem for me, unless I need to do more than that?
