Optiplex Sound Problems

Yes, there's an audio device on the motherboard (an ADI, sometimes known as Soundmax).

Some of the Optiplex models also have an internal speaker, though I'm not familiar with how they're set up.  Though you also have external jacks for headphones/speakers.

In general, though, "sound doesn't work" isn't really enough to go on.  Could be the speakers, the jacks, a driver problem, a settings problem, or a Windows problem.  Have you tried other speakers or headphones?  Did the sound ever work?  Did you reinstall the OS?  What do Control Panel - Sounds and Audio and the Device manager say?

Thanks for the info Alexandra.I will explain better. I have my speakers working on my monitor. I am running ubuntu on this 170L mobo which I put in a Compaq case!! Is there a small speaker on the mobo? Because i do not see it. In had to turn it on in Ubuntu. Just trying to clarify for myself.

Holy cow .  If I'd have known that I'd have just kept quiet :emotion-4: . The internal speaker I was talking about would have been part of the original case, not the motherboard - just a substitute for external speakers.  Here where it would be in a  small-form factor 280: <ADMIN NOTE: Broken link has been removed from this post by Dell>   But most motherboards do have another tiny speaker for things like BIOS beeps, which is totally independent of the standard audio.  Where it is, I can't tell you. As for where the actual ADI device originates - whether it's integrated into the chipset,  or a separate chip,  or how it's wired,  afraid I have no clue.   And I know absolutely nothing about Ubuntu either.  Sorry.

I do appreciate your input. Do not be put off by the ubuntu. I have thee other Dells running xp and it is not alot diff except when loading programs. It is command driven. I am a beginner at it. That info was what I was looking for. Neither one was working when I posted. Everthing is working now. Thanks again.
