Dear list, I have an issue getting the optical connection on the Asus Xonar STX working in my system. The molex is connected, the card is found by the OS (Debian Wheezy), and the modules are loaded. I can see the device, and the alsamixer is available. In there, I unmuted the spdif/tos channel already, however, when I try to play to the tos connection using the aplay command, or VLC, I see no light at all coming from the cable or the port. The config (please disregard the USB, that one is working fine, but I want to switch over to TOS): aplay -l **** List of PLAYBACK Hardware Devices **** card 0: M20 [Meitner USB Audio 2.0], device 0: USB Audio [USB Audio] Subdevices: 0/1 Subdevice #0: subdevice #0 card 1: STX [Xonar STX], device 0: Multichannel [Multichannel] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: STX [Xonar STX], device 1: Digital [Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 aplay -L null Discard all samples (playback) or generate zero samples (capture) pulse PulseAudio Sound Server default:CARD=M20 Meitner USB Audio 2.0, USB Audio Default Audio Device sysdefault:CARD=M20 Meitner USB Audio 2.0, USB Audio Default Audio Device front:CARD=M20,DEV=0 Meitner USB Audio 2.0, USB Audio Front speakers surround40:CARD=M20,DEV=0 Meitner USB Audio 2.0, USB Audio 4.0 Surround output to Front and Rear speakers surround41:CARD=M20,DEV=0 Meitner USB Audio 2.0, USB Audio 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=M20,DEV=0 Meitner USB Audio 2.0, USB Audio 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=M20,DEV=0 Meitner USB Audio 2.0, USB Audio 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=M20,DEV=0 Meitner USB Audio 2.0, USB Audio 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers iec958:CARD=M20,DEV=0 Meitner USB Audio 2.0, USB Audio IEC958 (S/PDIF) Digital Audio Output default:CARD=STX Xonar STX, Multichannel Default Audio Device sysdefault:CARD=STX Xonar STX, Multichannel Default Audio Device front:CARD=STX,DEV=0 Xonar STX, Multichannel Front speakers surround40:CARD=STX,DEV=0 Xonar STX, Multichannel 4.0 Surround output to Front and Rear speakers surround41:CARD=STX,DEV=0 Xonar STX, Multichannel 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=STX,DEV=0 Xonar STX, Multichannel 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=STX,DEV=0 Xonar STX, Multichannel 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=STX,DEV=0 Xonar STX, Multichannel 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers iec958:CARD=STX,DEV=0 Xonar STX, Multichannel IEC958 (S/PDIF) Digital Audio Output My question: how do I play to the optical link so that I actually see the light coming on? thank you.
