Red Hat

I am not able to run any video file. Getting message something like : no audio facility.
Is this may be problem of driver. If so please send me link for the same.
I am working on Red Hat Fedora (Linux)

We cannot possibly help you with hardware problems without knowing what your hardware is.

What he said.

Need to know what architecture your computer is, version of RHEL, what sound hardware you're using (make and model) and how it's attached (ISA, PCI, USB, Firewire, etc.) also what modules are loaded (lspci), what your alsa.conf file looks like, and any relevant lines from dmesg or /var/log/messages.

I had installed the OS on my ACER (Aspire 5315) laptop. That's all. I hadn't installed any driver. So would like to get some assistance like any web link, etc. where I can get the reqd. driver file, etc. that will resolve the issue.

alsaconf is the command you run to configure ALSA. But first you need to identify your hardware and make sure it's supported.

Please post the output of the lspci command.

The same sound chips can be used in dozens of ways, but don't inform the OS of which way they're hooked up. Acer shipped your laptop with custom drivers to let it work in Windows -- Linux was not given the same courtesy. Linux doesn't know you've got an Acer, you've got to tell it.

You can tell ALSA via the option options snd_hda_intel model=acer

These instructions are for Gentoo but you may be able to find the equivalent file in RHEL.

Lupin, lspci command worked but for me to send you the output I need to copy the output from UNIX to Windows where I am using internet. For that I have to copy 1st in pendrive. Please let me know the device file name for pendrive in Linux.
