Playmaker plopping sound

I've recently sold my Playmaker because I did not need it in my setup anymore. It always functioned well. The buyer now tells me he has connected Beolab 1's to it and his speakers now give plops and static noise.

Does anyone knows what might be the problem? I've asked him about the RJ45/PL converter cables and he told he he tried several but keeps getting the plops.

Thank you for your thoughts and guidance on this matter.

That's a poser...I've had a PM connected to my system, into the inputs of my BS9000, for years now and have never heard any such thing, no plops or static. For a month or so at the beginning I had it connected directly to my BL9s, same thing, no noise or odd sounds. Could it be his speakers? Bad connection to the PL sockets? I've had noise in the past on my BL8000s when the PL plugs needed wiggling to clear up some misconnection or dirt on the plugs.

Your buyer is lucky at least his Playmaker makes a sound.

My Playmaker(s) most often made absolutely no sound as they refused to appear as a network device.

Thanks guys, I'm completely sure my PM works fine before selling so want to get more comfort that the problem may be the cables solely. Cannot imagine that the BL1's won't work with PM and that the PM is causing the troubles.

Regarding Airplay stability of the PM, that is another aspect with to my experience the stability was not 100% to my experience

My PM is quite stable, it will very occasionally have a dropout but very rare. I had issues at first, but only when streaming from iTunes on my PC, not with Spotify from my iPad. Turns out in my case I had an application that monitored the network on my PC that, when it requested network status, stomped on all other network traffic and caused dropouts. I now took that app off the startup menu and activate it only when it is needed then shut it down afterwards. Oh, I do run a fixed IP address on the PM, but even that didn't improve things until I stopped the network monitoring application on the PC.
