alsa-project/tinycompress issue #8 was opened from Andres6936:

I have compiled the program and when I run the `cplay` script I get an error:

```shellsession
andres6936 at Tierra ~/CLionProjects/tinycompress-master/src/utils $ cplay TestAudio.mp3 
Error: Can't find sync word
```

I have already checked out different mp3 files and I keep getting the same error.
I have also tried different options, but it is always the same error.
