Hello, Thanks for all of the information and discussion on this topic. I took a trip to a couple of audio hardware dealers yesterday and tried plugging in a couple of different audio interfaces to see if they would work out of the box with my laptop running fedora18. Here is what I found: The presonus 44vsl usb 2.0 was not recognized by my system. Upon opening system settings >> sound and then looking for the device under the "output" and "input" tabs, there was nothing to select except for my default on-board mic and speakers. The presonus 22vsl usb 2.0 provided the most hope of all of the devices I tried. I was able to select it in system settings and then also select it in the devices section of audacity's preferences menu. Upon connecting a mic and headphones I was able to both record into audacity and monitor output from audacity through the headphones. The one drawback I had with presonus 22vsl was that I was unable to play music from neither rhythmbox nor amarok. Just as important for me as recording and monitoring sound I create with audacity (or some other sound editing software) is the ability to listen to music for inspiration and new ideas. I could hook up monitors (speakers) directly to my headphone jack on my computer, but I'd like to take advantage of the preamps on board the audio interface. I then went to a second store and connected a tascom US-600. The tascom was not recognized at all by my laptop. I tried rebooting with the device connected and still nothing in system settings or in audacity. The final device I tried was the Focusrite 2i4. I was excited to see that it was recognized in system settings. I was able to select the Focusrite as an output device, but when I selected it as an input device my system settings window would crash. I was able to select the device for both input and output in audacity. I was able to listen to playback in audacity, but the unable to record into audacity through a mic. I still have not purchased anything. I'd like to hear some feedback on how I might be able to solve the issue with the presonus 22vsl not being able to output signals from amarok and rhythmbox. Thanks and hope some of you find this information useful. _______________________________________________ music mailing list music@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/music
