[alsa-devel] Idea about the laptop speakers

Hello developers,

some time ago, people complained that the sound came out from both the laptop speakers and headphones. While in many cases this is not desirable, I think this effect (when configurable via opening a different PCM) can be useful in the following situation.

Suppose that you have a laptop as your main working machine. The headset is always connected, but you are not always near the laptop (e.g., think better if you walk in the room). Then, you configure (by telling it to open different devices) your SIP softphone to play voice through headphones only, but play ringtones through both headphones and speakers. Thus, you can walk in the room without being afraid to miss a call.

Is the above proposal implementable?
