Hi, The regression was previously discussed on this mailing list last month (2017-10-04). As in the previous discussion, this commit restricts the supported sound formats to S24_LE. This problem is experienced in our iMX6q based hardware with SGTL5000 sound chip. I.e.: # arecord -l | grep 'card 0' -A2 card 0: imx6qba16sgtl50 [imx6q-ba16-sgtl5000], device 0: HiFi sgtl5000-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 In kernel 4.11.0: # arecord --dump-hw-params -D hw:0,0 2>&1 | grep '^FORMAT' FORMAT: S16_LE And in now in kernel 4.13.3: # arecord --dump-hw-params -D hw:0,0 2>&1 | grep '^FORMAT' FORMAT: S24_LE By reverting the mentioned commit 70d435ba1cd6, the format returned to S16_LE. However, I'm unsure if that is the proper way to solve this issue. I.e. does reverting the mentioned commit cause some other unwanted effect ? What would be the best solution that would make the S16_LE format supported again for SGTL5000 ? _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
