Cabal repl is unable to resolve dependencies

When I try to run it in cabal repl, it is unable to resolve depencies:

load music considered harmful?

sorry for the generic title.

I just finished debugging an issue where I used load to read a music file from disk and play it.
I also kept all the Music values I loaded in a Map.
I ran into all kinds of strange bugs, music jumping forward at a specific place,
trying to play music I already played wouldn't do anything after playing something else, music starting from the middle of the file, etc.

Then I thought that maybe the ByteString content of the file was garbage collected and/or overwritten or something. So instead of keeping a Map of Music I kept a Map of ByteString which is the result of readFile and I played music using playMusic Forever <=< decode. This fixed the issues I had.

Am I correct in my assumptions? Maybe the load API is problematic and should be removed?

I just wanted to share this so it might help others if they trip on these kind of bugs.

Thanks!

Randomly refuses to play

Hi ! It's been a few days and I've struggled with this bug as it seemed totally random. Basically I'm using the library to play a whole song, and short samples. Here is the code:

fileOn :: String -> Mix.Channel -> IO ThreadId
fileOn fpath channel = forkIO $ do
  music <- Mix.load fpath
  _ <- Mix.playOn channel Mix.Once music
  delayWhile $ Mix.playing channel
  Mix.free music

I've never had the short sample (<1s wav file) not play, but the long song (.mp3) refuses to show up randomly. It happens about 1/5 times on my fast computer, and 4/5 times on my friend's slower computer. Maybe this has nothing to do with speed, but I'll leave this there.
Maybe I'm calling this wrong, it's basically only used as a side effect in do blocks, and I do nothing with the thread id.

Sorry if it's all over the place, I can't figure out if the problem comes from me or the library.
Thanks in advance.

SDL2_mixer 2.0.2 breaks the build

openSUSE has recently updated its SDL2_mixer system library to version 2.0.2 and that change has broken the build of this Haskell package:

Is this a known issue?
