Hello, I have a thread I posted at diy-audio forums on this. My quest is to find a sound card compatible with Linux/ALSA I can use to create professional grade and home hi-fi equalization and crossover function. my search has led me to the RME cards, as I have a general requirement to implement sub-bass equalization below 20Hz (and RME can do 5Hz) and they appear to have excellent specs, however, as I understand it, I will need to purchase two output cards for the RME card in order to realize enough discrete analog output channels for active crossover of 2X6 (highs, mids ,bass). I may need to expand this to additional channels EG for dolby 7.1 home theater. I'm writing to ask about the RME cards relatively to Linux (I'm using Suse 10.1) -- which RME cards are the most fully-featured to work with ALSA in the various product lines? Which cards within those most actively "supported" by the driver developers are the most robust and the best cost/feature wise? Which have the most flexibilty? I originally looked at the RME 96/32 PAD because I have a Windows RTA where this card has been reported to work well... Now I'm pursuing Linux so I'm not so concerned about Windows... The replacement for the RME 96/32 PAD card is the HDSP9632 which has only stereo analog output. You need to buy the expansion card(s) -- apparently 4ch or I or O each card. The 9632 can handle supposedly 6 I/O simultaneously. Is my assumption I'd need one output card for use to implement a 2X6 analog I/O correct? My info from http://www.rme-audio.com/english/hd....htm#TECHNICAL. Which of the RME cards are most actively used/supported? Are there any other sound cards with similar characteristics that might be a better choice? Looking at the RME card, I'd need (I think) the card itself plus two 4-port output cards to realize the 2x6 crossover and EQ's -- I'd be spending about $1200 on the hardware. I can buy dedicated prosound or home hifi equipment (loudspeaker management system) to do the same for less money -- yet I'd rather implement in something like BruteFIR and Linux if I can avoid commercial equipment. Oh and one problem with the RME card is if I need onboard I/O cards, it will take up more PCI slots than I have (I only have one spare PCE card). I'd have to find a PCI extender etc. I wonder if I should look at a fully outboard firewire device? Thanks for your advice!
