Neither idle nor a marvel

I recently picked up a bargain from eBay, £90 including postage for PIKO BR 80, running, good condition, boxed, and it came with an unused / unfitted PIKO 36194 Analog Sound Module and 5v Smoke Generator, also unfitted. I wanted the BR 80 for the grandkids to play with so the added content was a bonus. Although I use DCC and so the analog sound module was not much use to me, I thought I'd give it a try to see what can be achieved. The module contains the sound board, an on-off switch and volume control that fits behind the boiler door, two reed switches that fit under the loco, screws and (brief) instructions. The YouTube video below shows the results. It creates some standing sounds when the voltage is high enough to power the sound board but not move the loco. These are okay sounding and include air pump, coal shovelling, whistle etc. Once sufficient voltage is achieved the chuffs start but they are way out with the wheel revolutions. There is no sensor so it can only work on detected voltage. The chuff rate does increase with voltage but it needs speeding up by a factor of 2 or 3. There is no way to adjust it that I can see. Placing a magnet under one reed switch triggers bell sound, and on the other side a whistle. The volume control works well and the speaker is quite chunky and has a tight fitting baffle so it is quite loud. The board contains a capacitor so sound continues over brief power breaks. So there are some good points but even if I used DC the out-of-synch chuff sound would drive me nuts. Have I got a faulty sound board? I'd like to hear from anyone else who has one of these.
