I have upgraded an old Compaq Presario 2200 laptop (2218RS) by maxing out its RAM, replacing its missing disk drive with a 160GB and its dead wifi card with a later model.  All has gone very well on this box, which I bought on eBay for (believe it or not) $1.04!  I have tried a few distributions, including PC-BSC, but in the end I installed VL 7.0. 

The laptop is running beautifully but for one problem.  There is no sound at all, from either speakers or earphnes, regardless of the distribution or setup used.  Running lspci -v as root, I get (in part):

00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 03)
        Subsystem: Hewlett-Packard Company Device 3084

        I/O ports at 1c00 [size=256]

Further, running lsmod gives:

It has been a long tme since I have had to do any problem solving of this sort, and never with a sound chip.  I've looked, but I can't see any obvious problems and neither can I find any sort oftest program or script  to test the onboard sound to determine if it's functioning correctly.  Can anyone help me out by seeing a problem that I'm missing or by suggesting a method of testing the hardware?

Thanks, Ed

It appears that the sound module is being used.

The first thing to check is that the sound is enabled
in the Bios (found notes about this problem).

Second make sure that the card is not muted.

You can also in the terminal try using this command:

alsamixer

See if the card is recognized.

Thanks for the advice!  I would never have thought of the Bios.  Alslaplayer showed the card just fine, but still no audio.  I checked the Bios, then rebooted and still no audio from the speakers.  So on spec, I plugged in the ol' Sennheisers ad voila!   It appears that my one buck computer's speakers are kaput ad not the sound card.  Well, what can you expect for a dollar and four cents.

Many thanks for your help!
