Hi Jakob,

Hi Fabio, that’s interesting.
Looks like the fsl,imx-audio-sgtl5000 sound card driver that is used on the imx51-babbage does not try to adjust MCLK in response to the playback sample rate.
The simple-audio-card driver does that (it calls snd_soc_dai_set_sysclk whenever playback starts).
Could you please test this with linux-next tree?
Looks like that the recent b0a7043d5c2c("ASoC: fsl_ssi: Caculate bit clock rate using slot number and width") would avoid the issue.
