Having moved my content to the cloud, my audio files are once again not playing.
Sugarsync used to allow direct access to files, meaning I could stream my MP3s via the Google reader player. They've now added an intermediary page which means this no longer works. Looks like I'll have to pony-up for a dedicated server after all.
In the meantime, here is a workaround: on Safari, go to a blog post, click play on the player, open up the 'Activity' page (under the 'Window' menu) and look for the Sugarsync URL. Double-click this and it should take you to the download. On Firefox, right-click to 'View Page Source', then search for the Sugarsync link.
