Subject: audiod: Avoid busy loop in standby/off mode.
X-Git-Tag: v0.4.2~4
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=e3af6b4410d78e266d5459063a31b2aadb055145

audiod: Avoid busy loop in standby/off mode.

Without this patch, must_start_decoder() incorrectly returned true if para_server
is announcing a stream but the audiod status is not on. This results in
status_pre_select() requesting a minimal delay.
