[SOLVED] QjackCtl-0.9.2 DBUS error at start-up.
15 March, 2021 - 21:15 — Neil Darlow
Hi Rui,
I fired-up the new QjackCtl-0.9.2 release (AppImage) and it pops-up the Messages window and Error dialog with the following displayed in red:
20:59:34.553 D-BUS: SetParameterValue('engine:clock-source', 'h'): Parameter value type mismatch: was expecting 'u', got 'y'. (org.jackaudio.Error.InvalidArgs)
You can dismiss the Error dialog and start-up appears to continue OK but I thought you might want to know about this.
EDIT: I had the clock source set to HPET (which worked with earlier versions), changing this to Default prevents the error from occurring.
ATB,
Neil

which was the earlier qjackctl versions? and probably more importantly, what is your current jackd2(-dbus) installed version?
cheers

re. QjackCtl-0.9.2 DBUS error at start-up.
well, you didn't tell which qjackctl.AppImage version though your jackd2 version (1.9.12) is pretty old anyway...
please consider an update to the latest jackd2 (1.9.17).
cheers
OK, so am I correct in
OK, so am I correct in stating, from your previous response, that:
Changes introduced between qjackctl-0.9.1-45.x86_64.AppImage and qjackctl-0.9.2-46.x86_64.AppImage require me to upgrade my jackd2 above 1.9.12 in order to use HPET as the clock source?

re. OK, so am I correct in...
not quite... :)
after all that said, you were correct in the first place: there's a BUG indeed in v0.9.2 when setting the clock-source over jack d-bus... ouch!
you don't need to upgrade anything as with jackd2 v1.9.17 you'll certainly get the same error :( however it's kinda a no-op error or warning: it's only the clock-source setting that gets overlooked--all the rest seems to work fine though...
so, if you rely on setting the clock-source to anything under jack d-bus you're better use qjackctl v0.9.1 alright! or you may not use jack d-bus interface at all and things might work better in that particular regard (but surely get way more complicated on others like, for example, pulseaudio integration and what not).
sorry for all the misleading replies.
cheers
[UPDATE:] please test the just arrived hot-fix: qjackctl-0.9.2-47.x86_64.AppImage ;) thanks.
Hi Rui,
