Have you tried solution 6 of http://tex.stackexchange.com/questions/273483/revisiting-tipa-and-fontspec Basically you should not use the tipa package but use the texipa macro of the fontspec package. I have never used the IPA module in LyX but you may have to tweak it to suppress the loading of the ipa package You redefine the IPA environment for compatibility reasons with qtree. If Arial has the ipa glyphs you can keep the font for typing the ipa text. If not, you have to instruct fontspec to use a font with the available glyphs as explained above. Cheers, Charles
