I have never been aware nor perhaps the author that "hw" imposed any restrictions. However, "hw:0" and "hw:1" have always worked. # "surround41". In Quisk, all PortAudio device names start with "portaudio". # A device name like "portaudio#6" directly specifies the index. A name like # "portaudio:text" means to search for "text" in all available devices. And # there is a default device "portaudiodefault". So these portaudio names are useful: #name_of_sound_capt = "portaudio:(hw:0,0)" # First sound card #name_of_sound_capt = "portaudio:(hw:1,0)" # Second sound card, etc. #name_of_sound_capt = "portaudio#1" # Directly specified index #name_of_sound_capt = "portaudiodefault" # May give poor performance on capture # In ALSA, soundcards have these names. The "hw" devices are the raw # hardware devices, and should be used for soundcard capture. #name_of_sound_capt = "hw:0" # First sound card name_of_sound_capt = "hw:1" # Second sound card, etc. #name_of_sound_capt = "plughw" #name_of_sound_capt = "plughw:1" #name_of_sound_capt = "default" sample_rate = 192000 name_of_sound_play = "hw:0" # Panadapter: Do not play channel_i = 1 # Soundcard index of in-phase channel: 0, 1, 2, ... channel_q = 0 # Soundcard index of quadrature channel: 0, 1, 2, ... microphone_name = "hw:0" # Name of microphone capture device (or "hw:1") mic_sample_rate = 48000 # Microphone capture sample rate in Hertz, must be 48000 or 8000 mic_channel_I = 0 # Soundcard index of mic capture audio channel mic_channel_Q = 0 # Soundcard index of ignored capture channel # Microphone samples sent to soundcard: name_of_mic_play = "hw:1" # Name of play device if mic I/Q is sent to a sound card mic_playback_rate = 48000 # Playback rate must be a multiple 1, 2, ... of mic_sample_rate mic_play_chan_I = 0 # Soundcard index of mic I play channel mic_play_chan_Q = 1 # Soundcard index of mic Q play channel mic_out_volume = 0.7 # Microphone output volume (after all processing) as a fraction 0.0 to 0.7 Regards Sid. -- Sid Boyce ...
