Hi,
I'm using Proxmox for a few months now and I'm very happy with its capabilities. There's a small issue which I can't resolve with the documentation and Google.
I have made a passthrough setup with a PCIe soundcard (Orban 1101e Optimod) using the following conf:
Problems arise when I copy data (audio files) from a remote network share towards the second local disk (vm-115-disk-1.raw). On that case the audio stream itself starts to stutter. Not the encoded audio but the audio generated by the music player. Assigning more memory or more cpu doesn't seem to have a positive effect, it continues to stutter whenever data is copied.
I was thinking it might be a bandwith issue from and towards the passthrough'ed soundcard. Does anyone have an idea how to monitor its usage to see if this hypothesis is right and even more important; a clue how to fix it. (e.g. using prioritization for the pcie passthrough).
Thanks in advance for thinking

The virtual machine is running Windows 2012 R2 hosting a music player which uses the orban soundcard to process the audio and then comes back into an audio encoder application to stream the audio to a different shoutcast server for use in internet radio.
