Subject: Avoid audiod hangs when prebuffer filter is active.
X-Git-Tag: v0.6.3~17
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=1eeb434d731702fd5c0c85c62bf6d18dd3463d8a;hp=b3c68fd8519a426d6b6285dcb5a865670285e99a

Avoid audiod hangs when prebuffer filter is active.

This filter misses to honor task notifications. As a result of this
omission, when CTRL+C is pressed while audiod is running in foreground
mode and the prebuffer filter is active, the audiod process hangs.

The fix is obvious.
