Hi guys! I have this problem long time. The overheating may not explain the issue, however the issue itself is closely connected to the power management of the hardware.
I investigated the problem and it is basically caused by the decision of the HW to switch the mode of the circuit (programmable HDA switch). Of course as the HW is programable, there is something (I would call it for now codec) that causes the HW beahavior. If the driver for the behavior is the increased temperature (and I believe it is), is secondary. The problem is that the 'codec' together with the Toshiba Satellite L750-129 HW and others (even other brands) is doing bad job. I tried to investigate the problem in order to fix it, however I found I lack of knowledge about complex HDA firmware programing so I withdraw the idea to fix it.
