However, pll_rate is only updated in\natc_pll_init() and not in hw_pll_init(), so it remains 0 after the\ncard init.\n\nWhen spdif_passthru_playback_setup() skips atc_pll_init() for\n32000 Hz, (rsr * desc.msr) always becomes 0, causing the loop to spin\nindefinitely.\n\nAdd fallback to use atc->rsr when atc->pll_rate is 0. This reflects\nthe hardware state, since hw_card_init() already configures the PLL\nto the default RSR."
