* audio: add support for multichannel HDMIEric Laurent2012-06-011-0/+7
| | | | | | | | | Added a dedicated audio output stream for multichannel HDMI. This output stream is used when an HDMI sink supporting 6 or 8 PCM channels is connected and 5.1 or 7.1 multichannel content it played. Change-Id: I7ad1cd6be4c2b3a9e24a4811aa87e7223badedc4
* audio: add support for deep PCM bufferingEric Laurent2012-04-301-0/+7
| | | | | | | | | | | | | | | Implement one output stream with short buffers and one output stream with deep buffers. The stream with short buffers is selected for most use cases and provides short latency. It uses TONES_DL port and IOCTL write mode. The stream with deep buffers is used for music playback. It uses MM_DL port and MMAP NOIRQ write mode. The deep buffer stream is not used when the device selection is BT SCO, HDMI or SPDIF. The echo reference is only taken from the short buffer stream.
