[oe] Openembedded and Gstreamer

[Alberto Milla]

I try

#gst-launch --gst-debug=*:3 audiotestsrc ! audioconvert ! alsasink

and I obtain the next output: http://pastebin.com/EVQjRVqS

where I can see 3 warning at lines 57, 58 and 59:

alsa gstalsa.c:124:gst_alsa_detect_formats:<alsasink0> skipping non-int format
alsa conf.c:3952:snd_config_expand: alsalib error: Unknown parameters
{AES0 0x02 AES1 0x82 AES2 0x00 AES3 0x02}
alsa pcm.c:2202:snd_pcm_open_noupdate: alsalib error: Unknown PCM
iec958:{AES0 0x02 AES1 0x82 AES2 0x00 AES3 0x02}

and from the line 75 I get a dump that starts with a:

0:00:02.183681854   953    0x15050 INFO   GST_EVENT
gstevent.c:1091:gst_event_new_latenUnable to handle kernel paging
request at virtual address aafaaaae

Can it be an alsa problem?
