WebSDR, Iceweasel, HTML5, fldigi - how to tie it all together?

["Andrew M.A. Cater" <amacater@galactic.demon.co.uk>]

Help, knowledgeable folk :)

A colleague is having problems with Iceweasel, WebSDR and feeding audio into fldigi.

This is on behalf of Martin, G5FM, who is also using Debian 7.

The WebSDR site he's using has just defaulted to not using Java and HTML5 for audio.
Whereas previously it was relatively straightforward to feed derived audio into fldigi,
this is now significantly harder as fldigi is more complex and has more options to set
than the version in Debian 6.

Ideas, anybody or advice on how best to configure this combination of software to work together
please.

Many thanks indeed,

Andy Cater, G0EVX
