some sound files do not play with some music players only under win 7
Here is a tough one for the audio gurus out there.
I have been recording lectures on my phone for years using a program called Easy Voice Recorder. It records in wav format. I transfer the files to my PC and convert them to smaller mp3's, which I typically play with winamp. I could of course also play the original wav files with my default player for those, windows media player (WMP).
This worked fine under winXP. A few months ago I converted to win 7. Now, when I play the wav files in WMP, the progress indicator moves along, but there is no sound. When I play the converted mp3's in winamp, the graphical level indicators bounce up and down, and progress indicator moves along, but there is no sound.
Before you tell me to turn up the volume, or turn on the speakers, or to select the right output device, note that when I play wav files from another source in WMP, there is sound. And when I play other mp3's in winamp, there is sound as well on win 7.
Furthermore, when I play the recorded wav files or mp3's with VLC, they do play and produce sound under Win 7. When I play the mp3's with another editing program called mp3 direct cut, they also play fine and produce sound under win 7.
Furthermore, when I play the same wav and mp3 files on another older machine still running XP, they still play and produce sound there as well.
So the problem is very specific - that recordings made with this software (Easy Voice Recorder), played with these players (WMP, winamp), on this system (win 7) appear as if they are playing, but there is no sound.
[The recording program is set to record at 16 KHz, with 16-bit PCM. I tried reducing that to 8 bit, but it made no difference. Also, the setting "use audio MIME types" is selected. Unselecting it also has no effect.]
What could this be?
Thank you in advance.
