https://bugzilla.kernel.org/show_bug.cgi?id=215561 --- Comment #11 from Takashi Iwai (tiwai@xxxxxxx) --- The "X" and "Y" are replaced with some numbers in the actual output. But the error messages might be already suppressed by the driver for some devices. Basically this is an old problem that surfaced now due to the commit forcibly initializes each mixer element at probe time. The patch like below should "fix" the problem, just by ignoring the error. Could you check whether it works? -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
