Through a quick look, there only a few commits between 4.9.27 and 4.10.15 regarding USB-audio. The suspicious one is commit fd1a5059610cd3887f1050171a840ca864108730 ALSA: usb-audio: more tolerant packetsize Could you try to revert this? thanks, Takashi -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
