Hi,I created a MR on slasa to fix this bug: https://salsa.debian.org/multimedia-team/flac/-/merge_requests/2 (also attached as patch).
I tested to build audiofile with the fixed flac version and it built fine. Best regards Philip

+Subject: [PATCH] Fix seeking bug
+
+Commit 159cd6c introduced a bug that only triggered upon seeking
+from the start of a headerless FLAC file to the first frame (so
+really not a seek at all). Furthermore that commit did nothing
+else in any other circumstance. This commit fixes that, by both
+fixing the problem and the behaviour the commit mentioned earlier
+meant to introduce.
