Audio waveform won't show in premiere pro even though tried several things

[sarab48445936]

Audio waveform won't show up even though tried several things - 

- made sure 'automatic audio waveform generation' checked in preferences 

- reset preferences

- deleted media cache (manually) 

- used clip -> generate audio waveform

- made sure 'show audio waveform' checked in timeline display settings

It's just driving me crazy! Anyone know anything else to try? Thanks
