Using the CD-S/PDIF In on a modified Audigy 2 (pins 25 and 35 patched, under Windows 7 and kX 3550) with analogue output, stereo works absolutely fine; what I want is to get 'S/PDIF-in AC-3 decode' mode working, however when I select it in the mixer I get nothing (on either peak meters from the DSP or the analogue speakers). The input over CD-S/PDIF is Dolby Digital 3/2. Here's the output from Input/Output Status: SPDIF Inputs: [R-Rate Locked; S-Stream Locked; V-Valid Audio] spdif A: 12000c02 Freq: 47999 [R] || max. 20bits/SR unspec. spdif B: unused spdif C: unused or same as B I2S Inputs: (0): 96000Hz [R] (1): 96000Hz [R] (2): 96000Hz [R] SPDIF Outputs: (0): 2109204 (1): 2109204 (2): 2109204 (24 bits / 48000 Hz) SPDIF Extended status: (0): 24bits/48000Hz (1): 24bits/48000Hz (2): 24bits/48000Hz p16v: PB: (bypass) I2S Out:96000Hz SPDIF Outbypass) Rec: (0): 0 (1): 0 (2): 0 (3): 0 Could anyone provide me with a solution? It would be greatly appreciated. Thanks.
