@Tim and Jussi,

I tried to find the same machine as yours in our office, but there is no 9i, c930 or c940. Please do one more test, then I will ask for help from Realtek according to the test result.

Boot with the standard kernel (not my testing kernel), play some music through the speaker, open a terminal, run alsamixer,

1st test: set the DAC1 volume to minimum, and set the DAC2 volume to maximum, could you still hear the music? Does the sound comes from front speaker or rear speaker?

2nd test: set the DAC1 voluem to maximum, and set the DAC2 volume to minimum, could you still hear the music? Does the sound comes from front speaker or rear speaker?

thx.
