Just to make it clear for the reminder of this discussion: we're talking
about using the ALSA-to-jackd bridge, your wording was a bit misleading.

The problem referenced there was a known deficiency in ALSA-plugins, but
it's fixed upstream:


Unfortuantely, there is no official release, yet. (latest is 1.0.24, and
this doesn't contain the fix)

However, you can compile alsa-plugins from git yourself:


@Debian-Alsa-Maintainer: Maybe consider updating to the git version or
backporting the fix.
