No Audio from DVD, CD, or VCD

___________________________________________________
Description
No sound is heard from the internal or external speakers. The notebook may also seem slow to respond due to hard disk performance. This behavior occurs after the notebook has resumed from standby or hibernate.
In the Device Manager, the properties of the IDE channel to which the drive is connected, under the Advanced Settings tab, may show that the current transfer mode for the drive is PIO Mode.
Solution
Examine the properties for the Primary IDE channel:

Click Start > Control Panel > System.
Click the Hardware folder tab, then the Device Manager button.
Click the + sign to expand the IDE ATA/ATAPI controllers section.
Double-click Primary IDE Channel Properties.
Click the Advanced Properties folder tab.
Examine the Current Transfer Mode setting for Device 1. If it is set to PIO, exit the Properties screen and proceed to step 7. If not, refer to the Fixing Sound Problems document below.
On the Device Manager screen, right-click on Primary IDE Channel. Select Uninstall.
Close the Device Manager window and reboot your notebook PC.
Repeat steps 1-5. The Current Transfer Mode setting for Device 1 should now read, Multi Word DMA Mode 2.
