Fix Shoutcast streaming on Spotiamp

If you’ve tried to use Spotiamp and realized the shoutcast server won’t start (with an MP3 codec error), you just need to make a couple registry changes.

Convert instances of l3codeca.acm into l3codecp.acm.

  1. In HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\drivers.desc there should be a REG_SZ value named “C:\Windows\System32\l3codecp.acm” (or simply “l3codecp.acm”) with data of “Fraunhofer IIS MPEG Layer-3 Codec (professional)”.
  2. In HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32 there should be a REG_SZ value named “msacm.l3acm” with data of “C:\Windows\System32\l3codecp.acm” (or simply “l3codecp.acm”).

There shouldn’t be any instances of l3codeca.acm remained. Remove if any.

If you have Spotiamp up and playing with the Shoutcast server enabled and a computer tuned into it, the changes should have immediate effect. (The music should start streaming right away.)
