I am using a fresh install on my laptop. After setup, there was no audio output and the pavucontrol app was giving me the message:

Establishing connection to PulseAudio. PLease wait

After hours of load nothing happened and I tried the command pulseaudio --start, which temporarily gave me access to pulseaudio through pavucontrol. When I played a song, there was still no sound but it showed audio playing from both the output and playback.

I assumed it had something to do with alsamixer. In terminal, I then used alsamixer. I came to this screen:

Intel HDMI/DP LPE Audio

I also found this soundcard in the alsa mixer soundcards:

bytcr-rt5651

There were a lot of devices there where some were muted(MM) and some were unmuted(00). That's in the playback section. I tried to change all to 00, but the ones that were on MM returned to its default state MM.

With the alsamixer proving useless, I tried to uninstall and reinstall pulse and alsa by using the commands:

sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio

No result. I also attempted to use:

sudo alsa force-reload

No result either. I ran this: 

commandsystemctl --user status pulseaudio.service

which gave me the lines:

- pulseaudio.service - Sound Service - Loaded: loaded (/usr/lib/systemd/user/pulseaudio.service; enabled; vendor preset:

How can I fix this issue?

I need this laptop for school, which requires me to be able to use audio. Any help would be gladly appreciated.

  1. Blacklist the snd_hdmi_lpe_audio

    Create a file under /etc/modprobe.d with the name blacklist_snd_hdmi_lpe_audio.conf containing a single line:

    blacklist snd_hdmi_lpe_audio

  2. Copy the 2 folders bytcr-rt5651 and bytcr_rt5651 in /usr/share/alsa/ucm/

    (Download page https://github.com/plbossart/UCM)

  3. Restart
