If you want something that works without tweaks on a 600E, then I would try Win2000 not XP. The 600E was not designed for XP, and it was discontinued before XP was released. But lots of people love using XP on their 600E/X machines, and I think it can work well if you are not looking for ultra fast performance.
You are right that it does seem to be a common problem with XP on the 600 series, and I am not sure why. This is not a problem that I have had on my 600X machines.
Things to check:
1. Make double-sure that you have not disabled sound using the hardware mute button (Fn + Backspace).
To fix this, you should be able to simply increase the volume by using Fn + PgUp several times. I think this will produce a beep sound even though your sound is not working, and it will resolve your problem if your sound is in fact working fine but just muted.
2. Try removing the audio device and allowing it to be rediscovered.
For some people this seems to resolve the problem, but only until their next boot. When re-installing, if you are given a choice, try manually choosing the correct location for the drivers or the correct driver type instead of letting Windows choose for you. According to one forum member,
choosing the driver manually helped them resolve the issue.
3. Do you have the latest BIOS?
I don't recall where I saw this and don't seem to be able to locate a reference any longer, but
at one point I believed for some reason that this audio problem may have been resolved by updating to the latest BIOS. And someone over at the Lenovo forums seems to have the same idea (see
600x sound driver problems in xp home sp3 [forums.lenovo.com]). Certainly, if you don't already have the latest BIOS, then you should update to it if you are planning on sticking with XP because the latest BIOS in all 600 series machines (600, 600E, and 600X) includes specific fixes for XP. There are two different BIOSes for the 600E, and you have to get the one that matches your machine:
Drivers and software - ThinkPad 600, 600E, 600X
Please let us know if any of these work, or if you figure out how to fix it. This is a common enough problem that it would be nice to have a concrete explanation and resolution for others in the future.
