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?
