Lubuntu no sound at all; no mute, alsa, pulse

Question

Apologies if this question has been answered already but I've scoured these forums and I haven't found anything that works.

I recently put together a low spec machine with plans on running Lubuntu 12.04. Installation went smoothly however there is no audio whatsoever.

I've tried installing pulseaudio & alsa mixer, made sure auto mute was disabled and played around with all of the settings to no avail.

I previously had installed Ubuntu 12.04 on the same machine and there were no audio issues, only when I made the switch to Lubuntu.

My machine's specs are:

AMD E-240 APU

2 GB 1066 RAM

AMD Radeon HD 6310 onboard graphics

Realtek ALC887 audio chipset

I am very grateful for any and all feedback. Thanks!

Solution

In terminal run pavucontrol

1. In Configuration tab for Built-In Audio
