My (Debian unstable) Audacity 1.3.9 has input selection capabilities as has every version I've used since 2001. Edit..Preferences..Devices..Recording..Device. hw:0,0 is default, and I've played around with 0,1 and 1,0 when I was using a SoundBlaster Creative Live breakout box. As far as I'm aware alsamixer (1.0.20 on my system) always uses 0,0 unless you tell it to use an alternative device with the switch -D. Each device will have a separate Capture control for the individual inputs available on that interface. I believe Audacity is dependant on the settings you use here, so unmute everything and set volumes to ~72%. > Problem: On two Squeeze systems I have found two distinctly different > versions of Alsamixer both labeled version 1.0.20.

If so, maybe one has inputs disconnected or there is a hardware fault. > sources. While playing a cd I tried selecting capture from cd with no > effect. When I switched to capture mix the vumeter bars on Audacity Maybe you do not have the small wire from the optical drive connected to the soundcard required for direct audio monitoring when playing CDs. I presume you were trying to do this purely for testing purposes. If you believe Audacity is not functioning correctly there are plenty of other capture tools available: ecasound, arecord (part of the alsa-utils package) and rec (part of the sox package) are three examples, which work beautifully off the command line. > space bar.

Have you tried alsamixergui? This may help to understand the available functions of the chosen device. If this all doesn't help, maybe tell us what sound device(s) exist is on the PC you are using.
