Thank you, this looks like a nice interface indeed, and buying it second hand sounds like a viable route. It seems that a mix of all outputs is being sent to the phones output at the front[1]. Is it channels one and two? Since you mention that it is not class compliant but "supported", does this device have specific alsa drivers?
Yes, this device has a specific ALSA driver: https://www.alsa-project.org/wiki/Matrix:Module-ua101 https://github.com/torvalds/linux/blob/master/sound/usb/misc/ua101.c Regarding the Monitor/Phones output: That's honestly a very good question since I usually use outputs 1+2 only but have my speakers connected to the Monitor ports so I can use the UA-101's hardware volume knob to control the speaker volume. When using it for live shows (FoH audio), I usually connect the mixing desk's Monitor/PFL output to the inputs on the UA-101 and then the Input/Output-Blending-Hardware-Knob is used to blend from PC audio playback to Mixing Desk's signal (to headphones in that case). I just did a short test and sent audio on outputs 3+4 as well and it was also on the Monitor ports. With the proprietary Windows driver, there is a mixer tool one can use to configure this routing and mute certain inputs/outputs on the Monitor outputs but no one ever implemented that for Linux. The device's alsamixer only shows one digital toggle regarding MIDI. So, theoretically you could configure the device's routing using Windows once (to only have outs 1+2 on the monitor) and then use it on Linux. Or someone implements the mixer part for Linux ;) Not the best situation but sufficient for my needs.
The larger UA-1000 might even support coaxial SPDIF I/O, Wordclock and ADAT. I never had one in my hands, unfortunately.

It seems like the UA-1000s ADAT output merely mirrors the 8 analogue outputs but does not provide more channels in addition sadly.
True, seen from the USB side of things, it's still a 10in+10out interface, just with more flexible IOs. One note on the UA-101 and "class compliant": I have two UA-101's here, one is Cakewalk-branded, the other one is "Edirol"-branded. On the Edirol one, one of the DIP-switches is labelled "Hi-Speed". This actually turns it into a 2in+2out class-compliant interface. Maybe not really an option but a nice feature anyways. Don't know if the Cakewalk-branded one behaves the same and they just didn't label the switch or if it's just not possible with that one. https://www.manualslib.com/manual/315020/Edirol-Ua-101.html?page=14 Jannis _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
