Hi Audacity, I started this thread on a support ticket and was advised to switch the conversation to here. Here is the body of that email.
I down;loaded your program for Mac and, when it’s working it seems really good. My issue is that it seems to work at first but then it will not actually play an mp3 file which I reopen it the program. This appears to be true even for the mp3 files which are created by Audacity and exported to a desktop. When I choose to open them, the look to be fine with waveforms in place etc. but when I play them there is a crackly click in the beginning and then no sound and the cursor scrubs the track. The waves can be seen visibly dancing but no output. I have tried the online suggestions of changing preferences in the recording panel but with no success. I downloaded the program three times and reinstalled still with not success. Would love to use you if I can sort this out. MAC OS 10.9.5 on 2.53 GhZ Intel Core 2 Duo Macbook Pro
Or tried deleting the audacity.cfg settings file then changing Audio to
buffer if necessary: Audacity Manual > ?
If this is an external audio device you should also try the suggestions
here in case it is a sample rate mismatch problem: Audacity Manual> .
Another idea may be to turn Wi-Fi off. It can degrade audio significantly on battery-powered Macs.
If the sound fails with a click and then the playback cursor moves at normal speed with no audio, try playing some audio in QuickTime or iTunes.
Can you please as requested tell us what version of Audacity you are using (see the pink panel at the top of the page) and what exact device you are using for playback (make and model number if it is an external interface)?
I am a total amateur at this but I have had no problem at all doing what you are having trouble with. I just drag&drop the mp3 onto the
Audacity field. Then it lets me do “whatever”. I’m using OS 10.10.5 Yosemite with Audacity 22.214.171.124.
Do you have your system preferences (Sound) set properly?
