Foobar can't play 48khz IMA ADPCM 2017-08-16 02:00:33 IMA ADPCM isn't exactly a format that's used anymore, but I noticed that Foobar can't play 48khz IMA ADPCM. It just says "Unsupported Format or Corrupted File". It plays 44.1khz IMA fine, as well as 32. It plays 48khz MS ADPCM fine as well. It only seems to be IMA ADPCM that has an issue, and only at 48khz. I'm not sure what to do to fix this. Windows Media Player and VLC Media Player play them back fine.
