Re: Sound Blaster Livecrackles
This again usually happens to PCs using a VIA chipset, particularly the ones that has a 686B southbridge (KT133(A), Apollo Pro 133A/Z/T chipsets). A major symptom is that the speaker will crackle with static with or without music. Another symptom is that media files like MP3 will skip. Also, in some cases this problem will cause major file corruptions in the hard disk. There are many theories on this problem (do a Google search for that) Initally, some of the motherboard companies have a workaround with a BIOS fix. However, in order for the following to work you have to update to the latest BIOS version as the previous BIOS fixes may conflict with the proper fixes. One solution is to update the VIA Hyperion driver to the latest version. This helps in some cases but in some cases does not solve anything. Another solution is to use George Breese's unofficial PCI latency patch The stable version is 0.19d but does not support the latest chipsets. A third solution is to manually adjust the PCI latency value (if available) from 32 to either 0 or to 64. I don't recommend this unless you know what you are doing. In 2003, Creative finally releaased updated drivers for SB Live! and Audigy. The new drivers should solve the above problem for most people.

Does it have onboard sound as well, here is a link to the dell site and the manual, have a look as it does have onboard sound from Sigmatel STAC9220 so maybe two sound drivers are installed and conflicting
If you have the disc which came with the motherboard, use it to install the audio controller. However, you can just go to device manager by either:
For Windows Vista and 7
- Click start -> type in "devmgmt.msc" on the startsearch box -> press Enter key
Fow Windows XP
- Click start -> Run -> Type "devmgmt.msc" on the box -> press Enter key
In device manager, right click on the "Unknown devices" and select "Update driver" button. Search the web to find and automatically install the audio driver. (Make sure that you have an internet connection.)
The two most frequent sources for the loss of sound are bad connections and corrupted drivers.
To check connections make sure wires are not faulty. Check for crimps or damaged areas. Try a different set of speakers to see if they work. Make sure connecting plugs are placed in proper hole for sound out/speaker on back of sound card. If these check out and still no sound reseat the sound card [if not on mainboard sound] by turning off the unit, opening it [making sure to be grounded so no static electric discharge can damage the unit or its peripherals, then dismount the sound card from its slot after disconnecting all plugs attached to it, checking its connections for corrosion [this can be cleaned with a standard pencil eraser if any is noted], and reseating and securing it in its slot. Restore all connections and turn the unit back on and check for sound.
To deal with corrupted drivers check "Device Manager" to see if the sound card is showing a "bang" next to it [a black exclamation point in a yellow circle]. While not always present when drivers have become corrupted if it is that is most certainly the issue. Look up the support site for the manufacturer of the sound card or the chipset if it is on mainboard sound, and then download the most current drivers from the site. Installing them should overwrite any corrupted files and correct the problem if a corrupted driver is the source of the issue.
