However, the outcomes posted by David and Andrea suggest that in their particular laptops there is something *outside* the ALC260 chip itself which is preventing the speaker and headphone jack from passing audio. The alc260 test model provides access to almost all the control ports offered by the ALC260. If one doesn't get audio when using the test mode with all pins configured as outputs, everything unmuted and all volumes set to maximum, there's not much left at the chip level to try. For example there are some Acer laptops which appear to implement their own amplifier for the internal speaker which is only powered up when one of the ALC260's GPIO lines is raised. However, there's nothing stopping the manufacturers from using some other enabling mechanism and if this is done it's outside the scope of the Realtek chip; thus in this case Realtek might not have the information themselves to provide assistance. Having said all that I'm still hoping that there's something obvious I've missed in the test mode configuration.
