Hi guys,
I have a USB headset that the module is Edifier USB K800.
Plug it into the PC's usb port, and then I found "Digital Output
(S/PDIF)" audio port as below.
Would you please tell me why the Digital Output (S/PDIF) port has been
shown, and how to verify if this USB headset really have the output
function of Digital Output (S/PDIF), and how to close this audio port.
Thanks a lot!
Many USB sound cards show non-existent S/PDIF devices, probably because
the default configuration in ALSA maps both analog and digital to
device 0.
I think even a digital device can't be regarded as an S/PDIF device,
so we can use the iecset(alsa-utils) tool to double check to verify
if the device is really an S/PDIF(iec958) device.
Thanks,
Chengyi
