If anyone needs a decent, free signal source, the Tone Generator Ultra app for an iPod Touch will generate any audio frequency with sine, square or triangle. It has an option to enter note, which also shows the frequency. In its noise mode it wil generate white and pink noise. Spectral purity is not fantastic, but well within a semitone of true. Oscope waveforms look OK. Another free app, FreqGen seems to have better spectral purity, but does not have noise sources.
I have no connection with the app vendors, just a satisfied user. Neither app can replace a good bench signal generator, but is handy for quick checks and as a signal source for simple debugging. If you have an iPod touch (maybe works on an iPhone, never checked), they are handy to have.

sorry to say. The only other option is get a new player like the Oppo 93 or one of Pioneer's BD players that has PQLS over HDMI.
