Having obtained a solid 2ms latency at 48kHz with my Multiface II, I decided to shoot for 96. Partially I wondered if it might help with the loss of high end I was trying to troubleshoot in the earlier post about impedance matching -- I'm definitely losing treble somewhere. I've verified that I can compensate for it coming back into the mixer with EQ, but the point is, I shouldn't have to. CD's are only 44.1kHz, and they have no lack of treble at all. (Though it does often sound grainy or metallic to me...still, it's treble.) I can't imagine a reason that 48kHz should be dulling the top end. Anyway, the RME should be able to do 96kHz, so whether it solves the EQ issue or not, I wanted to try it. This is what I'm getting at just about any setting in the Jack messages: apparent rate = 96000 creating alsa driver ... hw:1,0|hw:1,0|2048|2|96000|0|0|nomon|swmeter|-|32bit control device hw:1 configuring for 96000Hz, period = 2048 frames (21.3 ms), buffer = 2 periods ALSA: final selected sample format for capture: 32bit integer little-endian ALSA: use 2 periods for capture ALSA: cannot set hardware parameters for capture ALSA: cannot configure capture channel cannot load driver module alsa If I set it to 3 periods per buffer, it just changes to: ALSA: got smaller periods 2 than 3 for capture All of this sounds like I'm just using parameters that the driver/card doesn't like. I'd be grateful for the information if someone who has a Multiface that works at 96kHz could post their Jack settings. I'm sure this must be possible, but I'm apparently just not asking for the right settings from the interface. The machine is a 3.2GHz AMD quad, so I've got plenty of system bandwidth, and the card is the PCI-E version. Addendum: This is what I get for not being satisfied. You'd think I'd quit when I got solid 48kHz, but nooooo... -- + Brent A.
