RuneAudio does play that sampling rate, but depending on the rest of your gear (type of DAC etc.), you may have issues with clean playback. 176.4 is basically 4x 44.1, and I have played test tones at that frequency just this past weekend.
Here is an example you can download and test, it is a small file, so you have to put RuneAudio on "Repeat" in the Play screen for a fair test:
Beyond that, you have to provide some information about the kind of DAC you are using, USB or I2S, etc., to get more help.
