I have recently installed Jammr but have been unable to connect to either a public or private jam session. Whenever I attempt to connect I have the following error:

There was a problem starting audio.

From what I have read this is to do with the connected devices. However, I do not know how to configure the settings within Jammr for the devices to connect correctly.

If anyone can help with how best to configure the Audio/MIDI/etc settings using a Line 6 TonePort UX2. I have also been using OnceStudio as well.

Look forward to Jamming in the future

Hi Ginger_Wookie,
Users have reported that the Line6 Toneport UX1 works fine so I hope the UX2 will work too.

Please go to Help | Show Log… and copy/paste the displayed technical information here.

You tried to use the onboard Realtek sound card as the playback device. Perhaps there is an issue with the 8-channel surround sound on that card.

The following should work:

Playback device: “Volume Control (Line 6 TonePort UX2)”
Capture device: “Digital Audio Interface (Line 6 TonePort UX2)”
Sample rate: 44100 Hz
Audio system: WDM-KS

Instrument and headphones attached to the Toneport UX2. Hardware monitoring disabled on the Toneport and the “Play back my audio” checkbox ticked in jammr's sound settings.
