Post subject:  Livewire HD output and sound card buffer problem

Hi

Configuration: Windows 11 Pro, ST 10.41, LiveWire.

I have a problem with HD output in ST.
The sound card is LiveWire and I have problems with sound quality, i.e. the sound is distorted.
A message appears in ST: Sound card buffer problem - HD Output. The HD Output card buffer id deviating too much from taget level. This is typically caused bu differences in exact clock speed between sound cards, and can cause audio dropouts.
I turned on option : auto-restart on buffer issues.
It helped, it's better, but there are still some problems.
What else can be done?

Regards

hi,

First, on the Axia IP Driver panel, set "audio level - nominal level of PC" to -20 dBFS (slider at the bottom left).

Second, now check if it's still distorted. If the distortion is gone, adjust the input level in Stereo Tool to about -6 dB.

Third, get a master clock if you want everything to sound OK (if you don't use an axia mixer or axia node)

Hi

Re 1. The audio level on the Axia Panel was set to -20.
Re 2. The input level is set to 0dB.
Re 3. I have an Axia node.

The distortions have not disappeared.

What else can I do?

In the xnode panel, in the mixer section, the Vmeters shouldn't be red.

It would help to understand your audio chain...
e.g.
Broadcast PC with Axia Driver?
Mixer?
Stereo Tool Input, Livewire?
etc.
