P2719HC, Brackets for AC511 speaker bars

This is very inconvenient about the speaker bars. My agency is in the same position of having several of these speaker bars and with Dell only stocking the new monitors, we would have to buy all new speaker bars just to get the mount. These speakers have the same part number as the old ones, so in addition to having to buy new ones that we don't need, the new mount has added an additional $20 to the cost of the speaker bars. The monitors and speakers both have the Dell name on them. This makes them Dell products no matter who manufactures them for the company. Does Dell care enough about their customers to fix this or do we need to start looking for other brands of monitors and possibly computers?
