On a recent thread on Reddit, i asked the question “What is your favourite rpg related podcasts?” After listening to a few of them I have picked out the ones that seem to be ones I will enjoy the most while working etc.
Happy Jacks RPG Podcast – a bit NSFW but very funny
Critical Hits – Not just a podcast but has other handy stuff on their site as well
Crit Juice – “A podcast following professional actors & comedians playing Dungeons and Dragons while under the influence.” – Enough said really
There are more suggested in the thread I linked, so go check it out
