Comment (by Klaas de Waal):

 I can reproduce this on today's master.

 The steps are:
 - In main menu, select "Watch TV"
 - It now plays either an audio or a TV channel
 - Change to another audio channel
 - Press Esc
 Now the never-ending stream of error messages appears:
 {{{
 2019-05-05 12:23:49.695885 I  Player(0): Waited 10ms for decoder lock
 2019-05-05 12:23:49.706023 I  Player(0): Waited 10ms for decoder lock
 2019-05-05 12:23:49.716184 I  Player(0): Waited 10ms for decoder lock

 }}}

 When "Watch TV" starts in an audio channel, it is possible to Esc back to
 the menu and select "Watch TV" again, any number of times without
 problems. It looks like the problem is triggered by the change to another
 channel.

 It does not make any difference if the channel change is done via the
 program guide or via the arrow keys (up or down) followed by Enter.

 It looks like it already goes wrong immediately after the channel change;
 although the channel does play the sound is initially stuttering and, more
 important, the following messages appear:

 {{{
 2019-05-05 12:33:01.043431 N  Player(0): Waited 105ms for video buffers
 AAAAAAAAAAAAAAAAAAAAUUUUUUUUUUUP
 2019-05-05 12:33:02.044140 N  Player(0): Waited 105ms for video buffers
 AAAAAAAAAUUUUUUUUUUUAAAAAAAAAAAP
 2019-05-05 12:33:03.111735 N  Player(0): Waited 105ms for video buffers
 UUUUUUUUUUUAAAAAAAAAAAAAAAAAAAAP

 }}}
 These messages are not present when the first audio channel is played.
 So after the channel change a TV channel, with video, is expected and that
 is clearly wrong.
