Bought for testing a SCADA driver that I had written to play a recording on loop when a particular SCADA tag was toggled. (The application here was audible alarms for a coal train weighbridge system. PortAudio + libsndfile, stuffed into a MacroView "sorted image" driver -- dynamically linked of course!) The only thing I note is there's a mixer quirk: they don't report the supported range properly and so `alsamixer` basically has 5 levels: 0 is off, 1 is quiet but still audible, 2 is a bit louder, 3 is basically normal volume. Full volume is 4, and anything above that is indistinguishable from 4. Other than that, they seem to work just fine for the times I use them. Definitely not audiophile grade, but good enough for casual use. -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere.
