Hello - I'm trying to get Waveinput working on Ubuntu 12.04:
1. Following cobbr2's helpful instructions (adding Squeezeboxserver to
the Audio group, etc) I can get hissing audio out using a wavin:default
url in LMS 7.7.2. Check!
2. I've got Audacity to record test sounds from the Alsa Host using both
'pulse' and 'default' inputs/outputs, so it looks like it should be
working. Check!
3. When playing around with Alsamixer or PulseAudio volume control the
amount of speaker hiss goes up and down depending on Mic Boost settings
etc, so I know the output is going to the squeezebox. Check!
4. ...but I can't get the computer headphone audio to be picked up. The
audio just doesn't come through. Fail :(
Note: Playing around with Alsamixer settings (Master, PCM, Mic, Mic
Boost / Capture and Digital) seems to work as expected when feeding
headphone analogue output directly into an amp (obviously the capture
and digital controls not doing anything). I've tried varying all the
playback and capture settings in Alsamixer, but without any luck.
Am I doing anything obviously wrong?
