Heill Konráð!

In Sognamålet, is there a distinction between voiced (unaspirated) and
voiceless (aspirated) stops, as in English d : t; b : p; g : k, or is
the distinction among the stops only between aspirated and unaspirated
(all voiceless), as in Icelandic? This is a feature which Scots
Gaelic shares with Icelandic, whereas Irish Gaelic has voiced stops as
in English. Scots Gaelic, which is now spoken mainly in the Hebrides
(ON Suðreyjar), even has preaspirated stops like Icelandic! Do these
occur in Norway? And does anyone know if they're used in the Orkneys
or Shetlands?

And in Sognamålet, do ON 'g' and 'ð' survive as fricatives in any
contexts, or have they become stops?
