After following the instructions in the manual to hook up the speakers, now when I play music on my main PC, I get feedback on the monitor (sqiggly lines keeping beat to the sound). No sound comes out of the laptop.
Originally didn't need sound so never hooked up the cable to KVM until a couple of weeks ago.
The only solution for great quality is to spend $150 more and purchase the higher end "Harmony" IO-Gear KVM switch, this works great! But if you don't want to spend that much, this is what I did with my IO-Gear GCS632U. I did RMA the first one and when the second worked the same way I realized I would have to live with it since I didn't have more to spend at the time! The video quality is terrible at high resolutions with this KVM, no MATTER WHAT!!! Playing with refresh rates helped a little, but I still saw some ghosting and interferance at times (most likely due to the lack of ferrite beads on the ends of the already "too small to carry a good signal" video cables), otherwise it looks and works great with resolutions under 1280x1024. The sound also suffers, obviously but I found out (using a multimeter) that the sound issue is due to the KVM unit trying to amplify the sound a little so to solve it I simply turned sound down in windows and increased the volume on my speakers until it sounded ok (if this doesn't work for you, try it vice versa).

Re: GCS632U - Speaker issues
To isolate the problem, please follow the steps below:
1. Connect first your speakers directly to the computer to see if the speaker is working correctly. 2. Checked the physical connection: make sure that your speaker is properly connected to the KVM and the KVM to the computer. 3. Make sure that you are going to play a music on the focused computer. 4. Make sure that your speaker is supported by this KVM switch.
NOTE: The GCS632U is designed to work with 2-channeled speakers only. If you are using 5.1 multimedia speakers, there's a possibility that it might or it might not work. You may refer to IOGEAR Web site and you will find this information.

With the GCS632U is recommended that you keep the KVM focus on a computer while it is booting. For example if both computers are turned off you can turn computer one on and the GCS632U should stay on computer one until it comes to a desktop. This allows the KVM to pass the monitor information and that may help.
The IOGEAR GCS632U is designed to work with VGA computers and monitors. Using the Mini DVI to VGA adapter is not guaranteed to work with this KVM switch.
The Mini DVI to VGA adapter can only convert the port, but it does not have an ability to convert the signal from digital to analog when it's connected to the KVM switch.
What you need to have is a DVI to VGA SIGNAL converter. Unfortunately, I don't have a model number handy, so I would suggest to contact IOGEAR, because I'm sure that they already have a work around with this issue.
Please make sure that the keyboard is hooked up on the KB port of the KVM. check underneath the GCS632U for the correct console port. you will see a keyboard and mouse icon. Make sure that the keyboard is connected to the keyboard port. tap scroll lock key twice to switch between computers.
GCS632U is designed to work with standard USB keyboard an mouse only. You have to make sure that you are not using any type of adapter such as PS/2 to USB adapter. To further isolate the problem, please follow the steps below:
1. Connect the USB keybord directly to th computer to make sure that the keyboard is working properly.
2. Make sure that the keyboard is connected to the keyboard port on your KVM switch. You may take a look under neath this GCS632U (near the USB ports) and you will see an icon where to connect the keyboar and mouse.
3. If you're still gettings the same problem, Try power cycling this kvm switch by disconnecting if from the computers and disconnect also the keyboard and mouse from the KVM switch and leave them disconnected for a minute or two.
4. Reconnect everything after two minutes and then reboot the two computers.
5. If same problem exist, try using different USB keyboard.
NOTE: This KVM swith does not work correctly with wireless, gaming and smart keyboards because it's designed to work with standrd USB keyboard only.
jerk_shop is correct, the GCS632U does get the power it needs to function from the USB ports of the computers it is attached to. Make sure the USB portion of the KVM cable is plugged directly into a computer without the use of any USB to PS/2 adapters. You will also want to make sure that at least one computer is turned in order for this KVM to function.
kvm switches are easy, they just dont look it with the number of sockets.
hook up your keyboard monitor speaker mic mouse cables to the output sextion of the kvm just as if you were hooking them to a single pc.
hook the cables from the pc-s as if the kvm switch were the peripheral devices,
so that all the outputs from pc 'A' are connected to the relevant inputs on 'A' side of the kvm,
all the outputs from pc 'B' are connected to the relevant inputs on 'B' side of the kvm
Operating System doesn't deal anything on your problem. The problem depends on the brand of you computers or the type of keyboard you are using.
The GCS632U is designed to work with standard USB keyboard and mouse only. And wireless and gaming keyboards and mice are not guaranteed to work correctly with this KVM switch. If any one of you is using the new Mac Aluminum keyboard, this keyboard will not work with the older version of the GCS632U. But IOGEAR releases a new batch of GCS632U that would work with the Apple Aluminum keyboard.
If you have an Apple Aluminum keyboard that does not work with the GCS632U, you may contact the IOGEAR Tech support and they will process a Return Merchandize Authorization (RMA) if your device is still under the warranty period.
To resolve your keyboard issue, try to power cycle the KVM switch by disconnecting it from the computers, disconnect also the keyboard and mouse from the KVM switch. Leave it disconnected for two minutes. After two minutes, reconnect everything and reboot the computers.
