Hi, By making slight changes in emufx.c, I could use all four spdif stereo channels of the sblive! that are present on the audio-ext connector. These spdif0..3 outputs can be accessed via: EXTOUT_TOSLINK_L,R ; EXTOUT_HEADPHONE_L,R ; EXTOUT_REAR_L,R and EXTOUT_CENTER,LFE. By re-routing "spdif", "front", "rear" and "center_lfe" to the respective outputs, four stereo signals (8 channels) can be simultaneously send to these outputs.
The "front", "rear" and "center_lfe" signals are alsmost perfectly synchronized (within a few samples) and the small delays are constant. However, the signal via "spdif" is not: its delay w.r.t. the other signals is about 60 samples and changes randomly every time the application is started. The "spdif" signal is taken from GPR(8) and GPR(9) in emufx.c. As far as I could backtrace these signals come from etram, which probably is the cause of the random delay. A solution might be to put the "spdif" also directly in two FXBUS registers (there are still 6 free FXBUS registers), as is done with the other signals. However, I don't know how to do this. I would appreciate any help or suggestions in routing "spdif" to an FXBUS. Thanks, Gerard Janssen ********************************************************************** Dr.ir. Gerard J.M.
