I’m encountering the same problem, I have some audio files which were natively in .ogg format and every file I try gives the error parth_phone2 sent a screen shot in of.
I have also tried re-exporting thee .ogg files in Audacity with a higher bit rate and sample rate and the same error occurs. I also followed partial guidance from the creator of a composer tool for PC which involves using the opus format as an ogg export, which also does not work, and I do not wish to get involved with a complicated an involved label tagging setup with added software to get this working, I was honestly hoping to see the automatically generated glyph visualisation at play for this.
Issue seems to have cropped up with others in my searches as of 2.5.5 and I am currently running 2.6 with all updates installed as of today.
