From: Shengjiu Wang <[email protected]> When stopping audio, ASoC will first stop DMA then CPU DAI. Sometimes there is a delay between DMA stop and CPU DAI stop, which triggers an underrun error. Now, because of the delay introduced by dev_err another underrun error will occur causing a vicious circle making impossible to stop CPU DAI.
