You can play them, sure, by converting them to PCM as dtc mentioned above. dtc means playing them back through bitstreaming without a conversion to PCM, this isn't possible over HDMI from any PC, Mac or computer. You either have to use DLNA (if it's supported) or do the DSD to PCM conversion.
For those who care about having a bit-perfect audio output this may be an issue, as a DSD to PCM (or PCM to DSD) conversion is 'lossy'. Granted, the OP didn't mention DSD in their post, so it's not known if playback of DSD is even desired to begin with so this discussion may not apply. And I'm sure someone else is going to mention this but to be clear, yes, if you desire a bit-perfect audio output you shouldn't do any sort of dithering, resampling (via SoX or otherwise) or using any DSP features like volume levelling and peak level normalization as it makes changes to the audio and thus makes it no longer bit-perfect. The benefits of using those DSP features like volume levelling may outweigh any potential downsides of it no longer being bit-perfect, but that's up to the listener to decide.
