This is something you might want to try. I have a feeling that some distros have a corrupt/incorrect asound.state being loaded:

$ sudo cp /usr/share/alsa/ucm/bytcr-rt5651/asound.state /var/lib/alsa
$ rm ~/.config/pulse/*
$ sudo alsactl restore

Ignore the following warning and your sound should be good to go!

alsactl: load_state:1683: Cannot open /var/lib/alsa/asound.state for reading: No such file or directory
alsactl: sysfs_init:48: sysfs path '/sys' is invalid

Found hardware: "bytcr-rt5651" "" "" "" ""
Hardware is initialized using a generic method

Make sure you save the current/new settings:

$ sudo alsactl store

 

It worked!!! Finally i can hear any sound from the chwui lapbook, maybe manjaro has the sound state corrupt or something but after this its working like a charm!! Thanks a lot dude you made my year!

I did blacklist the snd_hdmi, sorry i forgot to mention, but no results either 🙁 i feel like this is just a silly little thing missing to make it work.

@uno does this directory exist on your machine? /usr/share/alsa/ucm/bytcr-rt5651 If not, then try running the following series of terminal commands (script): #echo “Setup Audio for bytcr-rt5651” cd ~/ sudo mkdir -p /usr/share/alsa/ucm/bytcr-rt5651 wget https://raw.githubusercontent.com/plbossart/UCM/master/bytcr-rt5651/bytcr-rt5651.conf wget https://raw.githubusercontent.com/plbossart/UCM/master/bytcr-rt5651/HiFi wget https://raw.githubusercontent.com/burzumishi/linux-baytrail-flexx10/master/sound/alsa_ctrl/alsa_cr_spk.sh sudo mv bytcr-rt5651.conf /usr/share/alsa/ucm/bytcr-rt5651 sudo mv HiFi /usr/share/alsa/ucm/bytcr-rt5651 wget https://raw.githubusercontent.com/plbossart/UCM/master/bytcr-rt5651/asound.state sudo mv asound.state /var/lib/alsa sudo reboot # then try to play some audio … wget http://www.kozco.com/tech/piano2.wav aplay piano2.wav # If you hear nothing then #1 post the output of running this… dmesg | grep rt5651 # And #2 also re-run the Alsa info script and post the link again… bash alsa-info.sh

I dont have an ezbook, i own a chwui lapbook 15 which are pretty similar on specs, with this method i was able to get sound icon, device name and volume slider showing, but no sound on the speakers or headphones this is my output:

I tried to use blueetooth headphone and manage to make pair with the device but did not get any audio of it : (, also i tried  the new 4.13 kernel but nothing has changed to me either

[Pettrus]

Hello guys i don’t own a ezbook 2, instead what i have is the Chuwi LapBook 15 which is pretty similar to the ezbook, i tried a bunch of version o ubuntu and linux mint, some of them i got bluetooh working and wifi but they freeze after some time, or no freeze but got nothing working good enough, i tried respinning the ISOs but got no good result.

So i tried the new ubuntu, the one who ditched unity in favor of gnome(17.10 Artful which still in beta by the way), no respin or anything just a clean iso from the ubuntus website, and almost everything works fine.

• Wifi works out of the box, sometimes i get really low speeds or disconnects for no apparent reason but overrall is ok
• Touchpad is pretty good all the commands seem to work, 2 fingers scroll, zoom in and out, 3 fingers tab change, but it sometimes gets confused and zoom in instead of scrolling down
• Baterry indicator works good, without charging it has no problem,  but when i plug the cable it says its fully charged
• Bluetooh does not work, but i did not try to fix since is not a big deal for me
• No sound, which is the one that bothers me the most :(, Also i play a youtube or netflix video it looks like its 1.5 or 2x the actual speed for some reason

I am going to try to plug a bluetooh usb adapter and some bluetooh headphone and see if i can get sound, i will post back if i get any success.

One last thing, this is my sudo inxi -xxAv6AA to compare with you guys
