alsactl prints error messages from alsa-lib as is, and it's rather
annoying to see the error messages like

alsactl[xxx]: alsa-lib main.c:1405:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -6
that are recorded in the syslog at each boot.
This patch adds --quiet (or -q) option to suppress those error
messages from alsa-lib, and applies to the systemd services as
default.
The fix is inaccurate as it's just a warning not an error.
But it says "error" :)
The
question is, how to signal those warnings to users to eliminate the
confusion.
The suppression of all alsa-lib errors does not seem like a good idea to me.
At least the messages that are no real errors should not be shown in
that way. It's nothing but confusing.
From the UCM perspective, it's an error, because the configuration is
missing. UCM does not know anything about the legacy fallback. But yes, we
should not confuse users. I tried to fix this in another way. It should hide
only those specific messages.
