Hi guys,
I found that some usb earphones can match the device-strings hw:%f and iec958:%f of the default.conf configuration file at the same time, so two output ports will be displayed, one is the analog output and the other is the S/PDIF digital output. Is there any difference between these two outputs? Which device-string I should disable between hw:%f and iec958:%f? and how can I disable one of them? would you please help tell me, thank you! Below is the snippet from the configuration file default.conf: # Match the analog output [Mapping mono-fallback] device-strings = hw:%f fallback = yes channel-map = mono paths-output = analog-output analog-output-lineout analog-output-speaker analog-output-headphones analog-output-headphones-2 analog-output-mono paths-input = analog-input-front-mic analog-input-rear-mic analog-input-internal-mic analog-input-dock-mic analog-input analog-input-mic analog-input-linein analog-input-aux analog-input-video analog-input-tvtuner analog-input-fm analog-input-mic-line analog-input-headset-mic priority = 1 # Match the S/PDIF digital output [Mapping iec958-stereo] device-strings = iec958:%f channel-map = left,right paths-input = iec958-stereo-input paths-output = iec958-stereo-output priority = 5 Best Regards, Chengyi
