Saffire Pro 24 firewire audio interface recognized but loss of sound and system crash after audio playback

Hello. Thanks for the reply. Sorry for the delay.

Hi. Are you using HVM PCI Passtrough for your Firewire PCI card? or a dedicated Audio Qube? Or Qubes OS 44Khz 16 bit audio virtualization pass-through? And is it Qubes OS 4.2 or 4.1?

I had only connected the audio interface to the computer and selected it as the output through PulseAudio Volume Control. I am using Qubes OS 4.2.

I have, since your reply, tried HVM PCI Passthrough and setting up a dedicated audio qube.

The HVM PCI passthrough gives me an error of ‘qube has failed to start: internal error: Non-endpoint PCI devices cannot be assigned to guests’ when launching the qube. I haven’t tried any of the additional attach options due to security issues (I’m not sure if this step is necessary or the implications of doing so).

When setting up an audio qube using this guide, I am unable to create a file in dom0 at the ‘configuring policy’ section with ‘Directory separator illegal in file name’ error and so am unable to complete the setup.

@alimirjamali

P.S.: And what is your intended final use case? Only using it as a general output device for Firefox, VLC, … and day to day general usage? Or you need to use all 16-in/8-out 24bit/96Khz ADC/DAC channels and the DSP processor in a proper DAW such as Ardour or Reaper?

I need to use the audio interface with full capabilities in a DAW.

Just to note, the only devices I am able to attach in the qube settings are ‘PCI Bridge’ and ‘Firewire IEEE 1394’. There is nothing for the audio interface, however it does show up in the pulse audio volume control settings.
