Sometime in the last six months or so, alsa sound support has stopped working in my usrp_psr_receiver.py application, with the very helpful:
File "/usr/local/bin/usrp_psr_receiver.py", line 343, in __init__
self.audio = audio.sink(second_input_rate, self.audiodev)
File
"/usr/local/lib64/python2.5/site-packages/gnuradio/audio_alsa.py", line
236, in sink
return _audio_alsa.sink(*args)
RuntimeError: audio_alsa_sink
This is when asking for plughw:0,0 as the audio I/O device.
This used to work.
Interestingly, when I do an aplay -l from the command line as a regular
user, it can't find any sound devices, but when
I do an aplay -l as root, it can find:
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
I'm near-certain that at some point, some Fedora 7 update buggered up
something in the sound configuration somewhere, but
I'm not familiar enough with Alsa to know where. Can anyone help?
