Description (last modified by reimar)

When I resume my PC after software suspend with mplayer running on a local file, I get hanging sound and shortly thereafter mplayer crashes.

Apparently SNDRV_PCM_IOCTL_RESUME failed: Function not implemented seems to cause the crash. Even if this is caused by a buggy HW driver (linux 2.3.32), mplayer should not crash.

This bug still exists in MPlayer SVN-r32792-4.5.2 using Arch Linux with kernel 2.6.37-ck2 and alsa.

While mplayer is playing a file, when trying to hibernate using s2ram (or echo mem > /sys/power/state), i get (among other mplayer output):

[AO_ALSA] Pcm in suspend mode, trying to resume.
[AO_ALSA] alsa-lib: pcm_hw.c:709:(snd_pcm_hw_resume) SNDRV_PCM_IOCTL_RESUME failed (-38): Function not implemented

Relevant lspci -v output:

This is a 32bit Pentium M system.

Please tell us whether you need other information to help us solve this ancient bug. VLC has no problems and plays fine through the file when being interrupted by a suspend/hibernate.

This bug still exists with 3.0.22 when I use ao=alsa.
With pulseaudio (ao=pulse), this messages still occurs but after suspend/hibernate mplayer continues seemless to play video/audio.

comment:3 by reimar, 12 years ago

You write it crashes, but the quoted MPlayer output does not contain any crash message.
A gdb backtrace or valgrind log would help a lot, I don't have any hardware I want to risk using suspend on so I can't test myself.

the same for me.

Description: modified (diff)

That report also says it only happens with dmix, that IMHO would make it neither an MPlayer, nor hardware, nor driver bug but a alsa library one.

comment:7 by reimar, 10 years ago

Also, while the documentation is unclear, that patch you link to seems wrong to me.
It now always calls snd_pcm_prepare instead of snd_pcm_pause to resume.
On hardware that can actually pause/resume this should cause samples to be lost.

Did you see this commit?
"ao_alsa: Unbreak pause/resume"

It was done 3 hours after 4083ae1de37283210d022fb60b6128db276168d4
