Event History
Frequently Asked Questions
Which systems are exposed to the failure condition?
Linux systems using ALSA USB-audio are affected when a system resume occurs and either the PCM or mixer resume operation fails. The issue is tied to system suspend/resume handling, not the normal successful resume path.
How can I recognize that a device has hit this issue?
The USB audio card can remain unusable until reboot, with its control power state left at SNDRV_CTL_POWER_D3hot. Later control access can block in snd_power_ref_and_wait(), and USB core may log an interface resume callback error.
What can be done if the affected kernel cannot be updated immediately?
A reboot restores the card after the failure has occurred. The available data does not describe a configuration workaround that prevents the failed system-resume cleanup path.
Does the same cleanup behavior apply to runtime-resume failures?
No. The described cleanup is specifically for system-resume errors; applying it to runtime-resume errors would incorrectly alter the suspended-interface count, because runtime PM may retry certain errors without another suspend callback.
