I'm working on a script to set such a system up automatically. The idea is to start from a clean raspberry pi OS and then run the script to download and install l everything. What's missing now is the setting up of systemd services to have camiladsp and the GUI start on boot.
At the moment I'm busy finishing up the 1.0.0 release, but once that's done I'll get back to this.
Most all multi-channel USB DACs are limited to 192kHz or less, sans the exaSound DACs which support up to 384kHz. ExaSound supposedly wrote their own USB firmware/drivers.
Henrik: Thanks for your effort. I still have to submit the multirate patches (final version under review now) and hopefully a patch for the stream start/stop notifications (most likely using the Playback/Capture Rate control events). I have addressed several notable USB experts directly with the method options (apart of my mailinglist posts), so far no real response. But it will give in 🙂
I would be careful about the word "everything" 🙂 You may easily end up being expected to baby-sit every possible output device configuration, by those refusing to learn the very basics of command line. I guess you know what I mean 🙂
I think i have nothing higher than 192kHz/24bit. The 2ch SMSL Sanskrit DAC I'm using now seems to handle those fine. The multichannel Asus Xonar U7 also accepts the format (from memory), but the HW performance is not really at that level.
Oh no! Didn't think about this when I wrote that!
I meant not a completely clean RPiOS, but instead one where sound output is already configured. Then after running the script there will be a manual step of selecting the correct playback device and rate/format in the GUI.
