I've tried both the word clock and SPDIF approaches, without any success. Both the SPDIF Out and Word Clock Out connectors show no activity when inspected by an oscilloscope. Questions: - Is the word clock output something you must switch on in the ALSA driver or is it supposed to start automatically when you have a valid clock signal on the card? - Do I have to do something special to get SPDIF output (I'm new to this)? I've fiddled with iecset from alsa-utils, and otherwise I connected the SPDIF Out to various inputs using the patchbay of envy24control. Still, no signal appears on the connector. If it helps, here is /proc/asound/card0/ice1712: M Audio Delta 1010LT at 0xc000, irq 9 EEPROM: Subvendor : 0x12143bd6 Size : 29 bytes Version : 1 Codec : 0x1f ACLink : 0x80 I2S ID : 0x72 S/PDIF : 0x3 GPIO mask : 0x4 GPIO state : 0x7e GPIO direction : 0xfb AC'97 main : 0x0 AC'97 pcm : 0x0 AC'97 record : 0x0 AC'97 record src : 0x44 DAC ID #0 : 0x3 DAC ID #1 : 0x3 DAC ID #2 : 0x3 DAC ID #3 : 0x3 ADC ID #0 : 0x3 ADC ID #1 : 0x3 ADC ID #2 : 0x3 ADC ID #3 : 0x3 Extra #28 : 0x0 Registers: PSDOUT03 : 0x8080 CAPTURE : 0x55000000 SPDOUT : 0x0005 RATE : 0x08 (What do these numbers mean?)
