Bug#601652: need to delete cache or libffado2 fails

[Max Kellermann]

Package: libffado2
Version: 2.0.1+svn1856-5
Severity: important

The attached program fails when the libffado2 cache exists
(~/.ffado/cache).  It spills the following error message in
ffado_streaming_start():

libiec61883 warning: iec61883_cmp_create_p2p_output: Failed to set the oPCR[0] plug for node 0.

Deleting the cache (rm -r ~/.ffado/cache) will resolve the issue.

As far as I can see, there is no option to disable the cache.  A
shared library writing to the user's home directory is not exactly
good programming style anyway.

Severity important because it renders the library useless, unless you
delete the cache each time before you run a libffado2 application.
