Fixed sampling rate in jukebox mode

[glesik]

Thanks to @lxea for jukebox mode implementation! It looks like in its current form all audio is resampled to 48 kHz:

gonic/server/jukebox/jukebox.go

Line 76 in 6f02b58

sr: beep.SampleRate(48000),

The Beep wiki states that it's possible to use the sampling rate of the file being played. Can this method be used? Are there limitations to using per-file frequency (gapless playback issues maybe)?

[lxea]

I think it should be possible, I didnt look into doing that yet though. It shouldn't be too hard, taglib can get the sample rate I think. I'm not sure if the gonic db has it stored or If I'll need to parse each file again 🤔

[glesik]

Shouldn't the sampling rate be in format.SampleRate after calling streamer, format, err = flac.Decode(f) in doUpdateSpeaker? But then speaker is already initialized with some rate, right? Can speaker.Init be called right before speaker.Play?

Sorry if it makes no sense, it's the first time I look at Go code 😕
