Dell PowerEdge PERC RAID

Multimedia Audio controller Dell


We recently installed Linux Mint Petra on this small-form-factor dell desktop.

The weird thing is, the sound does not work on board, but works on a speaker connected to the audio out. I've checked all details I could about the alsa mixer, sound card mute check etc. All seems fine. Also looked to see if the box had any mute on/off button but there's none in sight.

Previously, when the box had Windows XP, there indeed was on-board sound, and thus there was no need to use external speakers for the audio.

Has anyone come across this issue, or is there anything else I could check. Any online search result only talks about general sound-card issues, but this is specifically a case of onboard sound not working.

Of course one could say why not just plug in speakers, but I would like to understand what the problem might be here and find a solution.

This question was seen as not relevant in the ubuntu forum when .
