Linux

I reformatted my hard drive and installed Mandriva 2011.
It works fine. I can go to the Internet

The problem is no sound.
I want to listen to songs from YouTube. Sound doesn't come.
I see a man is singing on the screen. No sound.
I had no problem with my old Mandriva. Sound and everything worked fine.

Your help is greatly appreciated.

What's your system?

I have a 64 bit PC. I have installed 64 bit Mandriva 2011.
I intend to install Fedora Core, Ubuntu, Open SuSe, etc.
I installed Mandriva on 'sda1'.
I have made 'sda2' , 'sda3' etc for other operating systems.
Every partition has 75 GB.
I will use GRUB to have other operating systems.

64-bit what? sound hardware is hardware-dependent.

Thanks for the reply. I looked at the details about the sound configuration and read the following
.................................................................................................... .....................................
Sound Configuration
Here you can select an alternative driver (either OSS or ALSA) for your sound card (VIA Technologies, Inc.|VT1708/A [Azalia HDAC] (VIA High Definition Audio Controller)).

Your card currently use the ALSA "snd_hda_intel" driver (default driver for your card is "snd_hda_intel")

Driver: snd_hda_intel[ALSA]

* Enable PulseAudio
* Enable 5.1 sound with PulseAudio
* Enable user switicihing for Audio applications [This is unmarked.]
* Use Glitch-Free mode

Yes...

But what is your computer? What brand, what board, what model, things like that. Sound is hardware-specific.

I don't understand what pulse is supposed to be good for. It just uses alsa, in the end, and just makes alsa harder to use...

[ The above shows the details of sound card, I hope.]
What shall I do?
