Why sound is not installing in my computer
Argghhh!...you need to configure your sound driver to work through the correct hardware you wish to use! (The best driver(s) for that require installation (or, reinstallation), if necessary.)
Are you using the onboard motherboard ports? HDMI-cable digital sound pass through? A PCI or PCI-EX sound card? USB speaker or dongle sound circuitry?
USB uses completely separate sound software and configuration control. It's "codec" is totally different and separate from other sound circuitry drivers. Sometimes, USB PC speakers merely use USB for power--not signal. Drivers and mixers for the relevant onboard or analog card output port then still serve.
Cables connected correctly? Jacks on your stereo or TV working correctly? Very rarely cables are defective or worn out.
Not getting sound is frustrating and bedeviling at times--you likely already succeeded, though. You're sound hardware likely is OK--that's rarely defective or broken.
Sound driver software configuration likely has a "Test" feature in some menu--when configuration is correct, invoking that will pump tone through each speaker--right, then left (then satellite speaker and sub). Perhaps more than one set of configuration settings are relevant, too. Make certain that the configuration settings you need are made visible in your mixer configuration, as well. (That's not always a "given.")
Know which sound system you're using--find then which drivers and configuration you need!
AMD Linux tips: The AMD HDMI driver for passthrough requires the binary "non-free" driver from AMD--open source drivers currently won't pass through HDMI signals. Enable the "non-free" repository. That's the way AMD desires it. They currently won't cooperate with the community on the open source HDMI sound driver (AMD won't yet provide source code--something upon which the community insists before they will collaborate directly on creating drivers--reluctantly, they will assent now, though, to allowing AMD (and others) to create proprietary binaries for our use--the community won't directly support them, though). Video passthrough likely will work nominally, though--providing video sans sound....
Another Linux sound tip--you need the correct "backend," codec, and mixer software for the sound software used--gstreamer, phonon, Pulse, ALSA, OSS, Jack, etc. Often, this proves necessary for initialization, enabling, and configuration in the first place. (Perhaps a simple "check" in a box is all that's needed--you may need to "tinker" in order make such a simpleton solution visible and usable, though.) The situation changes over time. Pulse is the default now--ALSA may serve up better, more usable mixers than the comically overly-simplified ones provided for Pulse....
