[PATCH 01/14] ALSA: compress: Update compress set params for gapless playback

[Mohammad Rafi Shaik]

Update compress set params for supporting next track settings
during gapless playback.
Update the runtime state to setup state only if it's in open state.
Allow parameter change only when stream has been opened and running
state.
