Hi,

Every time I am trying to connect to Jammr after using the computer for other purposes (with different audio configurations - like using laptop mic for conference calls, etc) I am reverting to computer sound USB input and Line output to match Jammr setup.
I am trying to reconnect using the same Jammr settings that always worked.
It never allows me to reconnect, hence the need to restart computer.
After that it works like a charm, although I do not modify any setting.
Is it anything I can do from Jammr settings or computer sound settings to avoid restarting computer before using Jammr?

Thanks,
Hardy

Hi,
jammr tries to load the sound settings from last time when you start. If the sound input/output devices have changed then it might fall back to the system's default sound devices instead.

USB devices can “change” if they were disconnected/reconnected or if they are multi-mode USB devices that switch between a driver installation disk and the actual device.

Please go to Help | Show log in jammr and copy-paste the technical information that gets displayed onto the forum so I can take a look at the sound devices. Thanks!

Stefan, thanks for taking the time to answer my question.
My system works with INPUT: Microphone (USB Audio Codec) which is the USB OUT from a Peavey PV10 mixer and OUTPUT: Speakers (Realtek HD Audio output) which I amplify separately from the mixer inputs in order to avoid any feedback.
Here is pasted info from Help log, not sure what time is this from as it differs from my actual clock, but it seems to show the mentioned struggle at the start.

Now I don't think the problem is from Jammr.

Thank you,

Hi Hardy,
Is that log output from a successful jammr start?

Does the Help | Show log output look different when you start jammr after using your computer for other audio tasks?
