           Summary: [alsasink] need to specify device for digital output,
                    despite having a setting for that
    Classification: Desktop
           Product: GStreamer
           Version: 0.10.25
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal

I have an integrated sound card (AMD HD audio, hda_intel driver) that behaves a
bit strangely with ALSA, but this sounds intentional. There are two devices in
/dev/snd: one corresponds to the analog output, and the other to the digital
output. There is also a checkbox, that I can make appear in
gnome-volume-control.gstreamer, that switches betwen analog and digital output.

Depending on this checkbox, regular ALSA applications (such as xine or
mpg321) use the correct output without any configuration.

With GStreamer, though, this is not the case:
    gst-launch-0.10 filesrc location=blah.mp3 ! mad ! audioconvert !
audioresample ! alsasink
→ no sound in digital output.

I have to specify the hardware device by hand:
    gst-launch-0.10 filesrc location=blah.mp3 ! mad ! audioconvert !
audioresample ! alsasink device="hw:0,1"
→ works fine.
