Archived:Poor quality when AMR-WB tones are packed inside a DRM message on S60 2nd Edition (Known Issue)
Sound quality is poor when an OMA forward-lock protected AMR-WB tone is downloaded and played with the Recorder application. When the same content is played with the Profiles application, the sound quality is good. If the tone is downloaded as a plain file, without the OMA forward-lock, the sound quality is normal.
How to reproduce
Wrap an AMR-WB type tone into an OMA forward-lock package and download it to a Nokia 6600 phone. After this, play the tone with the Recorder application.
Corrected in S60 2nd Edition, Feature Pack 1 and Nokia 7610 onwards. S60 2nd Edition, Feature Pack 1 is on top of S60 2nd Edition.
