Arch Linux

Description: Hi to all! I bought Creative X-fi Surround 5.1 pro to use it with Mixxx. This external card has 2 output DACs, according to 'aplay -l' there are to different "USB Audio" devices(USB Audio & USB Audio 1). In Mixxx preferences I choose "MAIN" as "X-fi 5.1 surround pro(hw:1,0)" and "Headphones" as "X-fi 5.1 surround pro(hw:1,1)", save them and try to run decks. But resampling in each of 2 decks going very slow with sound inhibition in every deck. Please, give me advice how to resolve the problem. When I choose in prefernces one of the devices above separetely of each other, decks playing perfectly. If anybody know how to make working this device and Mixxx(v1.11beta1) together, where the audio card has two independent audio channels for headphones and master.(My system is ArchLinux x64)


Steps to reproduce: Tryed to separate channels with jack2 and alsa_out but, after commutation in jack2
audio channels don't play separately, they are mixed, I wanted to make 2 channels to play for Hedphones and 2 channels for Master through separate audio outputs on audio card. May be I need right configuration for alsa for example "~/.asoundrc"
