I never needed anything<br>but two out before. Now that I look and digging through ALSA's<br>website, which has had some great updates in the knowledge base, I see<br>that there are some .asoundrc file tricks that have not been utilized<br>in a generic sense yet. The M-Audio FTP shows up as multiple cards and<br>each one shows up as a single device in Jack. I'm not sure how to<br>determine if they share a world/timing clock with each other, but it<br>seems that has to bind the cards/devices into one virtual device. I<br>have found the two places you can put an .asoundrc file, but ALSA<br>isn't reading for me. If one can get ALSA to read this when starting<br>this may be what is needed to get Jack to use all the devices as<br>outputs at the same time.<br>http://alsa.opensrc.org/index.php/.asoundrc#Joining_devices_to_make_multichannel<br>and http://alsa.opensrc.org/index.php/TwoCardsAsOne<br><br>I know I have the etc/modprobe.d/somename file being read correctly<br>because I am able to set the name of the for my M-Audio FTP. This is<br>more information you need to know about to try this:<br>http://alsa.opensrc.org/index.php/MultipleCards<br><br>I am at figuring out how to get the asoundrc file actually read.<br>Anyone know? I tried a .asoundrc file in /root for when I'm running<br>everything as root, but no luck yet.<br><br>-Sean<br><br>_______________________________________________<br>PlanetCCRMA mailing list<br>PlanetCCRMA@ccrma.stanford.edu<br>http://ccrma-mail.stanford.edu/mailman/listinfo/planetccrma<br></div></body></html>
