@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:

Please run the alsa-info script and post the link.  But prob better you create a new thread in the Chuwi forum section.

I don’t know.  Do you have pavucontrol (Pulse Audio Volume) installed? have you tried using that?  Try playing with the left and right speaker channels. Lower one channel to zero volume.
Probably best for you to open a kernel driver bug for this audio driver: http://alsa-project.org/main/index.php/Bug_Tracking

https://ubuntuforums.org/showthread.php?t=2358027&p=13675484#post13675484 This should be doable by adding the following like to /etc/modprobe.d/blacklist.conf: blacklist snd_hdmi_lpe_audio Once you have that reboot and verify that module snd_hdmi_lpe_audio is not loaded (lsmod | grep snd_hdmi_lpe_audio) (if it is then find a working approach to blacklist it, I don’t have Ubuntu actually). After you get it to not load, pulseaudio should run without crashing and audio should work. You may need to use pavucontrol to select speakers instead of headphones.

[Brad]

@uno, what was the meaning of your last post?  You did not say anything.  Did you blacklist snd_hdmi_lpe_audio?
Did you have some different results now?
Also, have you tried going through the Arch Pulse Audio troubleshooting guide? –> https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting

[Pettrus]

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.

Open alsamixer. Make sure the speaker is unmuted.

If it’s going to make it easier for you, here’s my preconfigured /var/lib/alsa/asound.state (now with correct left/right channels).

After unarchiving/copying it to that location, run:

sudo alsactl restore

@BC, So you have the speakers working on the EZBook 2 with this?
something else I saw maybe to check? –> (ACPI audio mode is chosen in BIOS)

Yes, speakers and headphones work quite well on my setup (AMI BIOS), except the sound quality on speakers is tin-canny.

Well can you post exactly which ISO you installed and and install method so other people can see if it works on their machine? It seems you are the only one who got audio working.

This is the install procedure as far as I can recall:

Grab the latest ISO (2017.10.01) from any one of the HTTP direct downloads on the Archlinux page: https://www.archlinux.org/download/

Burn the ISO to a USB drive:

# dd if=archlinux-2017.10.01-x86_64.iso of=/dev/sda bs=64M; sync

Eject the USB and reboot this time from the USB.

Enable wifi:

# wifi-menu

Get the assisted install script:

# wget https://github.com/helmuthdu/aui/tarball/master -O – | tar xz

Switch to the helmuhdu folder and run:

# ./fifo

When the basic Linux install is done and the system reboots, execute the following:

# echo blacklist snd_hdmi_lpe_audio>/etc/modprobe.d/modprobe.conf

That should prevent the HDMI from interfering with our rt5651 sound driver. Reboot again, switch to the helmuthdu folder and run:

# ./lilo

When you’re done and the system restarts, sound should be controllable from either the Gnome settings or pavucontrol.

The only sound-related thing right now that needs attention is the internal mic not working.

Good info.  Have you or anyone else tried to install the latest Antergos 17.9 (which is really just an Arch  installer)?  I wonder if that would work with just blacklisting the snd_hdmi_lpe_audio.  Or, is there some special “magic” that you know is baked into Helmuth’s Arch install scripts?
Do you know if Antergos can be installed onto a USB drive in data persistent mode (like you can with Manjaro) so that it could be tested without mucking with your fixed drive?

I haven’t really tried installing a new version of Antergos because I prefer seeing for myself which packages are installed to keep my setup as lean as possible. Having said that, since Antergos is really Archlinux with Cinnamon lipstick (I prefer Gnome), simply blacklisting snd_hdmi_lpe_audio followed by a reboot should be enough. The attached /var/lib/alsa/asound.state file will also help with the swapped left/right channels.

BTW, Helmuth’s install script allows you to choose your desktop environment. Only the installer is text-based but it is pretty automatic.
