| 159 | | - The 'interface' field should contain only a number. This number is |
|---|
| 160 | | the port number of the IEEE1394 host controller the audio device |
|---|
| 161 | | is connected to. For most people this will be '0', but if you have |
|---|
| 162 | | multiple controllers, you have to change this number. |
|---|
| 163 | | - The 'Input channels' and 'Output channels' fields indicate if the |
|---|
| 164 | | backend should provide capture and/or playback channels. If you set |
|---|
| 165 | | these to 0, no channels are created. In order to enable capture and/or |
|---|
| 166 | | playback, you have to set them to a nonzero value. |
