No sound in games on Lubuntu 16.04

[BaK]

Hi

I've installed Retropie, following this guide https://github.com/retropie/retropie-setup/wiki/RetroPie-Ubuntu-16.04-LTS-x86-Flavor, on an old Pavilion DV6 laptop running Lubuntu 16.04 x86.

I get sounds with the 'speaker-test' command.
'alsamixer' command displays the following settings:

Sound is enabled in EmulationStation (at 100%), I can hear tic sound when I browse my games.

But when I launch a game, of any console types, there is no sound output.

Where should I look to troubleshoot this?

Thanx! : )

No hint?

It'll help to give as much information as possible. The necessary information is detailed at:

I don't have any experience running x86 RetroPie, but I'm sure that which emulators you're using when your not getting sound will be of particular interest.

Thx mediamogul for your message!

Here comes what I can tell so far:
Hardware: laptop HP Pavilion DV6 1110ez

RetroPie Version: git show in the Retropie-setup dir give me this commit https://github.com/RetroPie/RetroPie-Setup/commit/40abf5146fd20a900a2e147ce59169f615f9f6e6
So I guess it is v. 4.3

Attachment of config files: Where do I find the .cfg used?

How to replicate the problem: launch a SNES game (or other emulators)

Make sure you have pulse audio installed or switch audio output driver via editing /opt/retropie/configs/all/retroarch.cfg or via the configuration editor on the retropie menu (available from the advanced mode of the configuration editor).

Sorry for the late reply...

I tried very briefly to get things working without success and finally took the easy way installing Xubuntu with which I don't have any sound problem.
