Hi there!  After the last update and reboot of my Sid system, I could no
longer hear sound output from any application.  I'm running per-user
PulseAudio, and ``pavucontrol`` said that no audio cards were being detected,
showing only a fake sink device.  The card was reported in ``dmesg``,
``lspi``, ``lsmod`` and ``alsamixer`` though.

Running ``fuser /dev/snd/*`` showed only the Timidity daemon having
``/dev/snd/controlC0`` open.  Stopping the Timidity daemon seemed to fix the
issue and running ``pavucontrol`` again reported the physical card.  Actually
I was then able to start the Timidity daemon again successfully without
breaking things.

Restarting the system made the Timidity daemon hold the card again until it
was stopped, so I stopped and disabled the daemon as a temporary workaround.

As I mentioned, this happened after a recent update and reboot, so the issue
may have been introduced by some update during June 2018.

Thank you very much!

Timidity breaks pulseaudio's built-in Analog stereo device AD1989B (Intel HDA) by blocking
pulseaudio's device access so that the built-in device is not seen by pulseaudio. It does
so without any warning to the user. As pulseaudio is the common audio foundation of many
linux systems any new package installation (or upgrade) that has the potential to disrupt
an existing pulseaudio installation should result in a clear blocking warning to the user.
This problem can be remedied by killing the timidity daemon and uninstalling the timidity
package - that however should not be neccessary as it should not have been installed in
the first place. Even for a veteran of linux audio problems like myself it took some time
to pin down the root cause of the pulseaudio problem. I'm not suggesting a technical fix
or policy fix, but it's clear that installation of a new package should not break the
proper functioning of an already installed high profile package like pulseaudio.
