S/PDIF 3&4 causes broken and garbled signal when using a different sample rate to the H8000. The same signal on S/PDIF 1&2 is fine. Setting SRC Mode on/off makes no difference. This is usually when the H8000 has an internal clock rate of 48k and the incoming signal is 44.1k. When both are at 44.1k both S/PDIF 1&2 and ?&4 sound fine. Would like to make use of S/PDIF 3&4 in with it's ability to route directly to Firewire Outs. Using S/PDIF 1&2 nows uses up a main I/O.
