* When the TonePort is used with jack in full duplex mode and the outputs are |
|
* not connected, the software monitor produces an ugly noise since everything |
|
* written to the output buffer (i.e., the input signal) will be repeated in |
|
* the next period (sounds like a delay effect). As a workaround, the output |
|
* buffer is cleared after the data have been read, but there must be a better |
|
* solution. Until one is found, this workaround can be used to fix the |
|
* problem. |
