[PROBLEM] Spotify playing slow

[Nutul]

...
so if that's what's up it will either be because of a modified connect string, or the other client is set to pay fast.

That's indeed the question, now...

Other thing being... URL protocl changed, so maybe now the speed IS required, and for some odd reason, if missing, it defaults to "slower"...

typedef speed_type enum {
  slow = 0,
  normal,
  fast
}

speed_type sp;    // defaults to 0 at compile time...

if (speed_param) {
  sp = speed_param;
}

I know this is weird, but computers do what you tell them to, not what you want. All is possible.
