ATV AirPlay audio out quality issues #4

Closed dwhiffin closed 8 years ago

dwhiffin commented 8 years ago

When an AirPlay speaker is set as the audio output for the Apple TV, the audio quality is poor when playing music. There are obvious pops and crackles throughout the song.

MrMC log ?

Perhaps something to do with lines 214-217 in that log? AirPlay has a max sample rate of 44100 - I have this set as the max bitrate in MrMC (I've tried all the options as well with no change). Is it still trying to force 48000?

enable debug logging might show more info.

I did, I think. It is turned on line 93. Sorry if I'm misunderstanding.

I have also some logs from Kodi tvos 30 December build which is before Memphiz pulled in some MrMC changes that caused later builds of Kodi tvos to have this same AirPlay issue. http://xbmclogs.com/pfoczzbdq So with these logs AirPlay is working nicely - I think line 42 and 1075-1077 are interesting as here sample rate 44100 is also availble (line 42) as it wasn't in MrMC and it is able to output using it (lines 1075-1077).

interesting

dwhiffin commented 8 years ago

Seems to be fixed on version 1.3 from the TVOS App Store and logs suggest that 41k sample rate is working fine now. Well done!
