Reproducible in the demo app?

Yes

Reproduction steps

Playback a DASH DTS Digital Surround audio stream on Nvidia Shield TV Pro (connected to an AVR via HDMI) running v2.17.1 Exoplayer demo app.
The DTS bitstream should be passthrough to the AVR for decoding. This works in earlier versions of Exoplayer, E.g. v2.11.8. In v2.17.1 the playback stops with a warning message, "Media includes audio tracks, but none are playable by this device".

Solution: To fix this issue, add the following to DashManifestParser.parseAudioChannelConfiguration()

  case "urn:dts:dash:audio_channel_configuration:2012":
  case "tag:dts.com,2014:dash:audio_channel_configuration:2012":
  case "tag:dts.com,2018:uhd:audio_channel_configuration":
    audioChannels = parseDtsChannelConfiguration(xpp);
    break;

These are defined in DASH-IF guidelines: https://dashif.org/docs/Audio%20Amendment%20to%20DASH%20IOP%204.3.pdf

Expected result

The DTS bitstream should be passthrough to the AVR for decoding.

Actual result

Playback stops with a warning message, "Media includes audio tracks, but none are playable by this device"
