I'm pleased to discover the laptop can handle 80 minutes of ecasound. rec also works fine. However a few issues have arisen: 1. Distortion results when recording from some sources but not others. ~ Yamaha amplifier 'minidisc out' connection, Cambridge Audio CD player out connection, Pioneer tuner out connection. If I record from a Sony portable CD player 'line out' connection, there is no distortion. It makes me suspect these devices are outputting more than line out volume. ~ They are all of good quality. Alteration of the input volume on the command line of rec doesn't alter this distortion. I've attached the ecasound -ev output. 2. The recording software stops if the source becomes silent, identifying it as the USB device fault: usbaudio: unregister dsp 14,19 hub.c: Cannot enable port 1 of hub 1, disabling port. hub.c: Maybe the USB cable is bad? hub.c: USB new device connect on bus 2/1, assigned device number 3 usbaudio: valid input sample rate 44100 <snip> I don't consider the USB cable to be bad as it records fine for a full length of 80 minutes as long as there is no silence. I'm using an Edirol UA-1A audio capture device, simply an outboard DAC. I would be grateful if any of you have comments or suggestions for me.
