However, on Acer Aspire 6935, it seems that the speaker pin 0x14 must be connected with either DAC1 or 2; otherwise it results in silence by some reason, although the codec itself allows the routing to DAC3/4. As a workaround, the connection list of each pin is reduced to be mapped to either only DAC1/2 or DAC3/4, so that the compatible assignment as in kernel 3.1 is achieved.
