Hello After starting successfully the USRP, the natural next step is to try out some example. Being a ham radio, I focused on 'hf_radio'.
I immediately got an ALSA sampling error: audio_alsa_sink[hw:0,0]: unable to support sampling rate 16000 card requested 44100 instead. ...then an endless flood of aUaUaU. I found in the archives that this problem was experienced by using usrp/usrp_am_mw_rcv.py or similar applications. The proposed solution is to pass to the programs the following option: -O plughw:0,0 This is OK for usrp/usrp_am_mw_rcv.py, but I've seen that hr_radio/radio.py does not accept such an option. By comparing hf_radio/radio.py with usrp/usrp_am_mw_rcv.py, I've seen that the latter creates the audio sink like this: audio_sink = audio.sink (int (audio_rate), options.audio_output, False) where 'options.audio_output' contains the string "plughw:0,0". Therefore I've naively tried to hack hf_radio by modifying hf_radio/output.py like this: self.out = audio.sink( rate, 'plughw:0,0', False ) but the hack resulted in a python runtime error. Does this mean that it is not possible to use hf_radio using 'plughw:0,0'? Well, I don't belive this... Any suggestion? T.I.A.
