Output loopback is a feature where you can record what you hear. The HDSP series of the RME interfaces provides this functionality at the hardware level and this patch exposes controls to enable or disable it per output (playback) channel.
This probably works on other cards but due to a lack of hardware it is only tested and enabled for the HDSP9632 card with this patch.
Should this patch be accepted a separate patch will be posted to https://github.com/alsa-project/alsa-tools/tree/master/hdspmixer which adds "LPBK" buttons to each ouput in the playback strip for the user to be able to control this feature from the user land. Users from Windows tool TotalMixFX should be familiar with this.

Thanks, applied now with a slight modification of subject and a typo correction in the patch description (it's always good to run checkpatch once before submission :)
