alsa-project/alsa-utils issue #157 was opened from aiChaoSONG: If we suspend the system while axfer is doing playback/capture, after system resumed, axfer stopped playbak/capture with: ``` Fail to process frames: Streams pipe error PLAYBACK: Expected 4611686018427387903frames, Actual 143392frames snd_pcm_drain(): File descriptor in bad state snd_pcm_hw_free(): File descriptor in bad state ``` You can get the failure by playing in a terminal with `axfer transfer playback -Dhw:0,0 -f dat -i -vvv -c 2 /dev/zero`, and run `sudo rtcwake -m mem -s 5` in another terminal. axfer should survive system suspend/resume, just like aplay. @takaswie FYI, thank you for creating this tool. here is how aplay handle this: https://github.com/alsa-project/alsa-utils/blob/a566f8a0ed6d7ca5fd6ae2d224f3f28654a2f3be/aplay/aplay.c#L1738 Issue URL : https://github.com/alsa-project/alsa-utils/issues/157 Repository URL: https://github.com/alsa-project/alsa-utils
