Hi all, I have been attempting to build up as much information as possible on the 2nd gen 6i6 in the hopes someone on the mailing list will be able to find a quick fix. The device is usable under linux only as a 2ch output device in it's current state using snd_usb_audio . And only if you have set Hardware mixer routing from the Proprietary Focus-rite app in Mac OSX or Windows first. The following link contains various USB Capture dumps doing different things with the DAC in various sates. There appears to be something odd with the way it enumerates sub devices on the USB port so attempts to pass-through to a Win10 VM via KVM fail. I think I can probably get this working if I pass the underlying PCI root device controlling the USB hub in it's entirety but haven't been able to do this yet. It also looks like there is a firmware load event happening somewhere. I am hoping the lsusb and the wireshark USB pcap dumps at the link might be of use to someone more familiar with alsa. Any help or requests for more information gladly accepted. I am away for the next week - but will try and get a successful init dump out of a windows laptop and add to the repository of dumps. https://drive.google.com/drive/folders/0Bw2fu74VAaO5bksyUEhMZDBtUE0?usp=sharing Kind regards -Joel New Zealand http://linkedin.com/in/aenertia _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
