James, Thanks! I'm happy you have found a minute to devote to the problem :-) 'lspci -vnn | grep 0401' output is: 02:02.0 0401: 1412:1724 (rev 01) As for a DAC in use, I didn't understand the question reason: the problem exists for *both* line and spdif outputs. At any case, I must answer :-) Card's DAC is a part of Wolfson's WM8770 codec, an external DAC is self-maded and based on AD1853 with non-inverting analog part.

We just need the output from lspci -vnn | grep 0401 And also which DAC is involved. ------------------------------------------------------------------------- Take Surveys. Earn Cash.
