We've been tracking a number of users in recent weeks with a Variety of late model Toshiba Core2Duo laptop who are experiencing significant audio difficulties dropouts, pops and clicks when playing using Traktor and several other pro or realtime audio applications. A number of users have delved into their problems and the combined consensus is that the root cause of the issue is the Fan controller for the laptop. Several users have reported workarounds with varying degrees of success most notably changing the Computer type in Windows Device Manager to Multiprocessor with results in complete loss of ACPI control but forces the fan to run always. This _could_ lead to other problems so proceeed with caution.
Toshiba are aware of the issue and several attempts to ellicit guidance and help were ignored or rebuffed by totally disinterested engineers who were totally unwilling to make any attempt at help at all. There presently is no fix from Toshiba for the problem and recent BIOS fixes released by Toshiba do NOT address this issue, as reported by actual users. It affects both Windows XP and Vista users.
This problem affects a number of different models of the Toshiba Laptop line, A complete list is not available but if you have a laptop you know to be affected by this issue please post your model number to this thread. One that is known to be an issue is Toshiba A135-S4407.
In the meantime if you have just purchased a Toshiba laptop with the intent of using it for Traktor then you should immediately ascertain whether you laptop is one that is affected and you should consider returning it to obtain a laptop that is not affected. As stated there is no help from Toshiba forthcoming and no guidance at all on when / if a fix is coming.
If you are presently contemplating a new laptop purchase and want to avoid these problems then you should not include Toshiba in your list of candidate brands, at least until this issue is fully resloved.

(As a qualifier for this: Until about 3 weeks ago Toshiba was in my top 3 laptop brands I recommended, I now actively discourage all potential buyers from purchasing Toshiba for this very reason. On average I would recommend 25-30 brand / models a month to people.)
