Pass-thru by just ticking a check-box? Uh? For AC3 pass-thru the apps
need to provide AC3 in the first place. And switching the apps to do
that is certainly nothing you can trigger by changing an ALSA mixer
control.

If you mean normal PCM SPDIF, then I can tell you that PA supports
that just fine. You can switch between analog and SPDIF during
runtime, without even having to stop your playback.

Dunno how else I could understand your remark, but to me it appears to
be just bogus.

Sorry, but this is just bogus.
