1. Can you configure Windows so that your interface is the default device for playback and recording, and then play a couple of tunes through Windows Media Player and post back on the results? If THAT still sounds bad, then there is likely a driver issue between the interface and Windows itself.
2. IF the above plays cleanly, try setting the interface to a Sample Rate of 44100 and an ASIO Buffer Size of 128, (if they use a different method for the buffer you may need to pick something like number of samples or something like that, and if so try to pick something that has a latency of less than 9 ms).
These settings are for initial debugging purposes, and if all ends up working you can try to improve performance, but I am just suggesting these as a starting point while getting it to at least sound cleanly.
SO, one the interface settings are made, PHYSICALLY cycle the interface, by turning it off and back on.PLEASE NOTE here that Sonar should NOT be running while you are doing the stuff in step 2.
3. Once the above is completed, fire up Sonar and go to Preferences>Audio>Playback and Recording, and select ASIO as the Driver Mode, then click Apply.
4. Now, go to Preferences>Audio>Device Settings, and make sure that the Sample Rate is set to 44100 and click apply. Make sure your playback and recording timing masters are set appropriately and note the latency values reported at the bottom. (I would like you to post those values to this thread, as well.
5. In Preferences>Audio>Devices, you should see your 1010LT present.
6. OK, so now start a new project, using the Normal template. Insert an audio track, select the audio track by clicking on the number of the track at the far left side of the track in the track pane. Once it is selected, it should highlight the track. Right-click on the track and insert the same song you had earlier played through Windows Media Playerr. Sonar will import the music file to the audio track, and this will take a little time. Once that completes, simply hit play or hit the space bar to begin playback, and post back to this thread on how the playback sounds.
7. IF the audio rack plays back normally, you should be ready to rock and roll in Sonar. If, on the other hand, things are NOT yet working, please post that back, so that we can look at some other ways of getting this working for you.
Thanks for your patience in running the above, I am just trying to go back to the basics to see what happens.
