| I dl this version this morning and I am unable to click on the Mixer.
| I am trying to rip LPs onto the computer and then copy to CDs
| I am using a Kenwood _ Audio/Video control center 60RS
| I have a Technics SL 300 turntable connected to AUX.
| I am using a y jack from record out to line In on the back of thecomputer
| When I go to the Mixer Toolbar I can not change the inputs. In fact
| it is grayed out.
The set up you describe looks OK ; you need to select line-in on Audacity's
mixer toolbar but the options are greyed out.
There are various possible reasons for this mostly dependent on what
operating system you are on.
The first thing to do is open Preferences > Audio I/O tab and check that the
playback and recording devices are explicitly set to your soundcard. Similarly
if you have multiple sound devices (e.g. built in sound and an external USB
adaptor) then you need to choose the ones you want to use in the Audio I/O tab.
Other possible reasons
Card Not Supported
This applies mainly to high-end multitrack cards under Windows, where they
don't use the standard windows mixer API and windows volume control, but
a custom mixer application which Audacity can't hook in to. In these cases
you need to select the recording settings and levels using the custom mixer
application shipped with the sound card.
In another extreme case it's possible your card only has one input source in
which case Audacity's input selector is greyed out as there are no multiple
choices to select.
OS X Not Supported
OS X has a very different audio hardware interface to most other operating
systems. As a result, there may be no (or greyed out) mixer toolbar, or only
one audio recording source available to Audacity, which will be identified as
"Default Source". You will need to use the Apple "Sound and Midi" Setup
utility to select the required recording source as the default one you want to
A lot of Windows computers seem to ship with only the default Windows
sound card drivers installed . Unfortunately the default driver for many
modern AC 97 cards is broken and does not support recording. This causes
errors if you try to record, and the input selector to be greyed out. To resolve
this you need to update the driver to the current version produced by the
card or motherboard manufacturer. This can usually be found on their website,
and will often unlock other features as well as making the card work correctly.
In Windows you may also be able to automatically update to the latest drivers
from the manufacturer using Device Manager : right click on the audio device
in Device Manager and click "Update Drivers". Do not use any drivers from
Microsoft as these are only generic drivers.
This usually means that the version of Audacity you have installed has been
built without input selector (portmixer) support. This could be because it
was built wrong, or because you have an (experimental) portaudio v19 version
of Audacity which hasn't got portmixer support. Help > About should give you
both a version number and a list of which libraries were enabled at build time.
Build from a package which has portaudio V18 or compile it from source
using portaudio V18. You can download the source cods here
or browse through it here

> This sounds like an ALSA driver problem - most likely the version of ALSA you have installed on you machine doesn't match the version of ALSA that gnome sound recorder was compiled with. This may well also be true for audacity, or the ALSA-OSS emulation that audacity (by default) relies on.
> If you start audacity from a terminal you may get more error messages as to what is stopping audacity recording. Does the red recording cursor move across the screen correctly when you try to record, or does the program just stick at zero?

If you need more help, please write back and tell us your operating system
and version of Audacity (Help > About)
| In addition to that I was not able to gather where to click in order tocreate a new project.
| Perhaps this option will become available once the Mixer toolbar isactive.
| Please advice.
| I am trying to record these for my daughters birthday.
