The reason for the need is to be able to hear when a "buzz" occurs. I do not want an incoming message sound, as this is annoying to have occur on every incoming message.
I'm not sure how having a "buzz" be audible is giving up any more control than an audible incoming message, already available in Pidgin. I would envision a feature where the "buzz" audible is allowed or denied, or where limits are set to how frequent a "buzz" is played, say maximum 2 per minute, or maybe 2 per hour.
I still need a resolution. This is an example of how some users who were accustomed to a certain feature available with Windoze turn away from Linux, since they feel they can't get what they want. Naturally, I understand that there are plenty of Linux features that you can't get with Windoze XP, but the people being converted don't care, they only know they are giving something up.
I will play with the pounce option, and see if I can work something out. In the meantime, if there are any other thought on this, I'm still interested.
