| Subject: [Audacity-help] No Sound
| The problem is no sound at all in Audacity when playing back files
| previously recorded in other apps. I have not yet recorded in Audacity.
| I do have the emu selected as the playback device for Audacity itself
| and as the soundcard for the computer in audio under control panel,
| volume up. It works at all other times with all other applications.
Have you got the volume slider in Audacity turned up (the left hand one in
the Mixer Toolbar)
There is a current problem that the Audacity volume slider seems to act
as a master volume control for the system on Windows, which was fixed
in a recent development version but has come back again in the current
Beta 1.3.2. This means that the Audacity slider must be turned up in order
to hear system sound.
| I do, however have system sounds turned off as a resource conservation
| measure, and because the Windows sounds are so annoying. This setting
| doesn't make a difference on the other machine, where Audacity is
| working, but I will try turning them back on and see if that makes a
It should not make a difference - how are you turning the system sounds off -
presumably on the Sounds tab of Sounds and Audio Devices, you have selected
"No Sounds" as the Sound Scheme? If you click on the individual sounds for
different events in the window of the Sounds tab, then on the Sounds dropdown,
you can specify what sound is used (or none at all for that event), and save
those choices as a custom sound scheme.
If the files that have no sound are Audacity Project files, the source files for
which are WAV files, those WAV files cannot be deleted or moved without
losing sound in the Project, if when importing them into Audacity you read
them direct from the disc. If this is the problem, the file(s) that you
originally used to read data into the project are marked as "aliasfile" in
the .aup Project file. You can open the.aup file in a text editor to see the
original location of these files, and if you can restore them to the path
noted in the .aup file, the project will have sound again.
To avoid this problem in future when importing uncompressed data, either
retain the original audio file or set Audacity to make a copy of the file,
which will then be stored in the Project's _data folder when the Project
is saved. You set Audacity to make a copy of the imported data by clicking
Edit > Preferences > File Formats : "when importing uncompressed audio....",
check the radio button "make a copy of the file before editing". Note this
issue does not arise if importing compressed data such as an MP3 file, as
Audacity automatically makes a copy upon import.
If none of this helps, please write back, and let us know the format of the
files e.g. MP3 that have no sound when imported into Audacity and if when
imported, these files have a waveform on the Audacity screen.
