Where can i find drivers to run.
|
Most common 'drivers' come with the OS. Ubuntu ships with may pre-compiled modules to make sound work.
First you have to know what sound hardware you have. To find out, open a command prompt. Run the commad '/sbin/lspci | grep audio' ( commands are run without quotes ) just enter what is between the quotes.
On the system I'm on now, it looks like this...

bash-3.1$ /sbin/lspci | grep audio
00:1f.5 Multimedia audio controller: Intel Corporation 82801BA/BAM AC'97 Audio Controller

Your output will differ, you probably have an Intel HD audio controller. ( Just a guess ).
Next, to find out if there is a loaded driver. Run the command '/sbin/lsmod grep | snd'
On My system this looks like this..

You will get very little if there is no module loaded to support your card.
Once we know what the card is, then we go to the Alsa site, find out what driver you need. If it comes with Ubuntu, then we use the command 'modprobe moduleneame' to load it.
If the driver did not come with Ubuntu, there may be source available. Then you get the source, compile the driver and load it.
Once a driver is loaded, you load a mixer, make sure the volume is un-muted, turn up the volume, and it should play.
For some very new hardware, sometimes there is no driver. Then you have to either write one, or wait for one to become available.
See what the commands tell you. Post the results. We'll go from there.
