Since I installed Win7 on the other partition, Aud135 (in linux) won't record from the microphone! (Both my sons say this is impossible, Dad is losing it.) I have ALL volume controls at max in <alsamixer>, and both sliders at max in Aud top left of window (although these don't seem to do anything?). There is no activity in the Recording level meters. Playback is unaffected.
Today (with SoundBlaster attached), Preferences/AudioIO/RecordingDevice gives me five choices:
None of these show any input from either the USBline or the ExtMic jack.
Help/AudioDevices shows the number of inputs to these devices as 16, 16, 2, 2, 128 respectively.
(I recently installed the LAME decoder, succesfully, but it hasn't affected the problem.)
I can't get Aud135 (in linux) to use USB for playback, either.
Same setup as above (and it all works
with Aud139 in Win7). Test track recorded earlier (in Win7) at 48KHz.
Today (with SoundBlaster attached), Preferences/AudioIO/Playback gives me 13 choices ("using Portuadio vn19"):
None of these give any output to USB, though the signal is visible in Audacity's green level-indicators. The ones with asterisks play OK through the HP530 internal speakers. Help/AudioDeviceInfo shows at least 2 output channels and 48KHz support for all 13 devices.
