Hi Robert, I'm here again to bother you guys on this nice mailing list: I configured BruteFir that, as Robert supposed, can handle more than one soundcard. I can run BruteFir, but I have a problem: when I activate more than one soundcard by BruteFir I can hear some "POPS" coming out from my speaker. Everything is fine activating only one soundcard. The soundcards are properly installed and connected by internal wordclock cable: so two cards are slaved to the master one clock (this is done by HW settings, I cannot find any information about how to set one card as master and others as slaves, which is required, for example, under Windows). A CD player is connected to S/Pdif input of master soundcard, and this card is setted up by Envy24 Control utility to generate internally a 44100Hz clock, while others inputs are empty. I tried to set the card to get the clock signal form s/pdif, but BruteFir returns a "broken pipe error" with this setup. This setting can be made only on one card by Envy24 Control utility: I do not know if it is normal dueing to internal clockword connection between cards. I was wondering if "glueing" my three cards into one card as Robert suggested could solve the "POPS" problem. Unluckily I have no idea about how to do it, I'm quite new in Linux world and any help would be really appreciated! Thank you very much in advance to everyone who can help!
