What packages are necessary for a computer to have sound?

[Shabakthanai]

Dear Snowhog,

Just to be clear, I am answering this post in my Windows 7 OS. System Sounds are working fine, and the DVD player includes sound too.

When I attempted to open the Kubuntu 13.10 USB 3.0, I got some error messages; the first part I did not get all the message, because it changed screens faster than I could get a pen and copy all. It started I believe with Invalid Cluster Error.... Next screen is as follows:

[1.893753] Kernel panic - not syncing: UFS: Unable to mount root fs on unknown-block (0,0)

I restarted twice with the same result, so something is amiss with the USB 3.0 Thumb, I guess.

Next, I downloaded the most recent Kubuntu 14.04 LTS and made a successful USB 3.0 ISO stick.

It opened and selected 'Try Kubuntu'. There were NO system sounds. When I attempted to open System Settings to further check sound, System Settings opened in the other Screen, and the mouse would not move to the other screen to select the application. Frustration abounds. New and never before experienced problems seem to occur almost every time anymore. Do you have any suggestions now?

Since sounds work fine when I open the alternate OS, Windows 7, doesn't it seem probably that the problem is a Kubuntu problem?

Can the problem on the USB 3.0 stick be repaired, or should I just format the stick and use for other things. I have a good fresh ISO install on a 4GB Transcend 3.0 USB thumb drive anyway. I was just thinking there might be something to learn from the repair.

Yes, use the Try Kubuntu option on the USB. IF you have working sound there, we know that your current issue is a configuration one, and that can be resolved.

Could this be a glitch in the kernel?

[Shabakthanai]

I have attempted all solutions that are provided in this post. I re-installed the 14.04 version of Kubuntu yesterday. Help has pretty much ceased. I am not getting anything that calls for a bug report. I purchased and installed a new sound card which seems to be recognized and installed properly. And finally, sound works fine int he Windows 7 version, so the motherboard must still be OK. Please don't tell me I have to use Windows 7 forever

[ubuntuku]

still no sound with your new sound card?

[Shabakthanai]

Nor on my onboard sound card either. It is the reason I purchased the sound card. I thought perhaps my onboard sound became corrupted. This is a very frustrating problem. All the normal solutions do not work, and the problem persists even after a fresh install of the Operating System. When re-installing the OS doesn't work and when there is no apparent problem with my hardware, and when the other OS in my dual-boot system has sound working fine, suggesting that both sound cards and my hardware are fine, I am totally stumped Oh, and when I try to find driver problems, there are no options for a different driver that make any sense. The only drivers that show up are those for sound/video for my Radeon card, and I am currently using the (recommended) driver.

It is starting to look supernatural, like demons in my system.

still no sound with your new sound card?

I feel a solution coming

[ubuntuku]

Is there an option in the bios setting to disable onboard sound?

btw please post the output:

I looked at every item three times and couldn't see anything that appeared to disable Onboard sound. I don't know why, but I am troubled. I have a poor memory, but something tells me that I disabled the onboard sound, even though I can't find it in the BIOS. I have been known to look straight at and not see things before, so perhaps I am overlooking something. I just don't know. My motherboard is a Sabertooth AMD, special for 8-core processors and extreme video and sound. 990FX as I recall. Can't find the box at the moment. If you need more MB info, I will find it somehow. Thanks for your thorough help, friend

[ubuntuku]

Have you tried playing with alsamixer settings as described in the following thread: http://ubuntuforums.org/showthread.php?t=915078. Play a music using smplayer while you toggling channels in alsamixer.

If still no sound, you can try blacklist internal soundcard by running the following command:

echo blacklist snd_emu10k1 | sudo tee -a /etc/modprobe.d/blacklist.conf

and reboot to apply changes

[Shabakthanai]

Still no sound. I am soooooooooooooo bumbed. Reinstalling didn't help, nor did anything anyone has suggested. I am so stumped, I don't know what to do. Thanks for trying.
