alsasink leaves sockets openned?

[Jorge Fernandez Monteagudo]

Hi!

Sorry, no GStreamer 1.0 test yet!

My first try is the alsasink, but alsa lib is not discarded! I'm reviewing the
gstalsasink.c code and it's seems ok. I would like to know where the sockets
are created...

I only have one device

root at igep00x0:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: igep [igep], device 0: TWL4030 twl4030-hifi-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
root at igep00x0:~# aplay -L
null
    Discard all samples (playback) or generate zero samples (capture)
sysdefault:CARD=igep
    igep,
    Default Audio Device

I've seen vlc creating the sockets when playing an mp3 but they are
released when is over. I've asking the same in the alsa mailing list. I hope
not to be the only one with this problem :)

Have you tried if it still happens with GStreamer 1.0 ?

Are  you sure it's the alsasink element leaking the fd and not libasound
for example? Does it happen with all devices, e.g. hw:0 as well? (in
case you use e.g. dmix).

Cheers
