Subject: HDMI Multichannel LPCM/RAW Support/Status
Date: Tue, 26 Feb 2008 21:11:17 -0500	[thread overview]
Message-ID: <001201c878e6$0a8245a0$1f86d0e0$@com> (raw)

I was just curious if there is any planned support for multichannel LPCM/Raw
audio for newer HDMI based chipsets. There are several matx boards with HDMI
1.1 and above compliance, which means they should be able to pass 8-channel
LPCM audio. Also, in HDMI 1.3 and above, Bit Stream passing is supported,
which actually should be easier, bandwidth wise, than LPCM. Multichannel PCM
(above 2 channels) was never an issue because SPDIF lacked the bandwidth.
After talking with some people in irc it seems as though the # of channels
setting in Alsa is only one bit. Thanks.
