libvlc_audio_set_track delays with :network-caching seconds ?

[dongxf]

Hi,
I'm using libvlc 3.0.7 to play remote mkv file through http, i set :network-caching to 10seconds, when i call libvlc_audio_set_track to select another sound track, there is no sound at all, until 10 seconds later the sound plays again and sound track changed.

then I tested :network-caching with 3, 30 seconds, when i call libvlc_audio_set_track, the sound mute for 3, 30 second before it can get back normal.

How can i solve this problem ?

Thanks !
