I am using an "m-audio fast track pro" usb sound card in conjunction with ALSA version 1.0.23. I'm currently experiencing some problems using this card's analog capture device. I am using the following command to test the capture device: arecord -c 1 -f cd -D plughw:1,1 test.wav This command usually works, and I am able to capture a clear audio signal. However, on some invocations of arecord the captured signal is heavily amplified with lots of digital clipping. Furthermore, once this problem appears, subsequent invocations of arecord continue to produce an amplified, heavily distorted signal until the usb device is power cycled. Once the device is reset, the captured signal is at a normal volume until the problem randomly occurs again. I haven't been able to predict when the problem is going to occur but I'd guess that the captured signal is distorted about five percent of the time. I'm new to ALSA. Can anyone shed some light on what might be happening here? I'm also interested in hearing the experiences of others who are using an m-audio fast track pro. .Lewis ------------------------------------------------------------------------------ Learn how Oracle Real Application Clusters (RAC) One Node allows customers to consolidate database storage, standardize their database environment, and, should the need arise, upgrade to a full multi-node Oracle RAC database without downtime or disruption http://p.sf.net/sfu/oracle-sfdevnl _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
