Hi Remy, I can't help you with your issue, but I at least can report my experiences with another HDSPe card. The following output speaks for itself. [rocketmouse@archlinux ~]$ hdspconf HDSPConf 1.4 - Copyright (C) 2003 Thomas Charbonnel <thomas@xxxxxxxxxx> This program comes WITH ABSOLUTELY NO WARRANTY HDSPConf is free software, see the file copying for details Looking for HDSP cards : Card 0 : RME AIO S/N 0x579bcc at 0xf7d00000, irq 16 Card 1 : TerraTec EWX24/96 at 0xd040, irq 16 Card 3 : HDA Intel HDMI at 0xf7e10000 irq 30 No Hammerfall DSP card found. However, hdspmixer works, but it seemingly is anything else, but close to the current version of TotalMix. I bought the card 6 years ago and never got access to more than 2 of the 8 ADAT I/Os. I'm using the RME card to mix music, because the audio quality of the analog outputs is superb, but if I should need many I/Os and lowest latency, I'm using a Focusrite Scarlett 18i20. In my experiences USB allows lower latency, than PCIe does, let alone that in my case all I/Os of the Focusride are available. With the HDSPe AIO Ardour with ALSA instead of jackd doesn't work. This seems to be an issue for some cards and at least the AIO is one of them. I used the RME card with an AMD machine and now I'm using it with an Intel machine.
