The commit b56fa687e02b ("ALSA: fm801: detect FM-only card earlier") rearranged initialization calls, i.e. it makes snd_fm801_chip_init() to be called before we register interrupt handler and set PCI bus mastering. Somehow it prevents FM801-AU to work properly. Thus, partially revert initialization order changed by commit mentioned above.
