Sound driver does not appear to show [Intel HDMI/DP LPE Audio]

[Richie Legend]

Using my Thomson Neo 10, which is a French made notebook with a UK qwerty keyboard, however it appears all support for this notebook is that all support is in other languages including french and it is not clear what the actual drivers are in order to attempt to find a way of installing it myself.

With Ubuntu and Linux you don't usually need to install any drivers. It does however look like pulseaudio is failing on the machine, which will cause loss of sound:

!!Sound Servers on this system
!!----------------------------

Pulseaudio:
      Installed - Yes (/usr/bin/pulseaudio)
      Running - No

To try and fix this, please run:

sudo sh -c "echo 'realtime-scheduling = no' >> /etc/pulse/daemon.conf"

and then reboot.

Thank you for getting back to me and for your suggestion and I did run the following command in the terminal;

sudo sh -c "echo 'realtime-scheduling = no' >> /etc/pulse/daemon.conf"

By doing that, the terminal asked for my password which I entered, however from that point it just seemed to be waiting for me to write another command.

I then restarted the notebook as you advised. Sadly this did not seem to make any difference as the sound icon was not even on the top right of the screen or did any drivers show up.

After I tried this, I restarted the notebook again and pressed F7 and opened up the BIOS, and went to the Chipset Screen, then I selected the South Bridge item, then clicked Audio Configuration item, there I selected on LPE Audio Support and I changed it from LPE Audio ACPI mode to LPE Audio PCI mode, the only other option on there was to disable it, mind. I pressed the F4 - Save and restart.

The sound icon is now showing on the top right as are two drivers;

Multichannel Output Atom/Celeron/Pentium Processor X5-E8000/J3xxx/N3xxx series PCI Configuration Registers

Analogue Output Atom/Celeron/Pentium Processor X5-E8000/J3xxx/N3xxx series PCI Configuration Registers

Sadly I still have no sound, any other ideas?

[Daniel van Vugt (vanvugt)]

It sounds like /etc/pulse/daemon.conf might still need fixing. Can you please attach yours here?

Hello,

I also have the Thomson NEO10 netbook (Atom-z8350) and struggled to find a Linux where sound would work, after getting everything to work fairly well. I eventually found that sound works in Ubuntu 19.10 with Kernel 5.3, anything lower (19.04, Mint 19.3) had the issue. It seems kernel 5.3 has made some enhancements to sound compatibility. :D

With only 2gb ram and running live, Ubuntu would freeze after about 5 minutes though so I ended up using Lubuntu 19.10 instead, which can still freeze if you have too many firefox windows open but is much more manageable. Neither detected my linux-swap partition automatically though so you might want to set that up somehow or make a swapfile either way (or not run the iso live like I'm doing) if you have the 2gb ram version of the NEO10.
