Hi, Alan I reproduced this problems with speaker-test. The channels are wrong mapped. It's strange that if use mplayer to run, it looks ok. I'm looking this problems, and try to find the root cause.

Thanks for replying. I tested it with speaker-test and xbmc babylon. Both had problems with channel mapping. I used this command: speaker-test -Dhdmi -c6 or speaker-test -Dhdmi -c8 alternatively you could try speaker-test -Dhw:0,3 -c6 I had to rund Xorg first and have the command from an xterm, becasue from a normal terminal it would not work. I think that is normal as a limitation of hdmi. What about the support for 24bits 192khz sound ? speaker-test -Dhdmi -c6 -r192000 does not work. Thanks for working on this. 2009/6/3 Wei Ni <wni@xxxxxxxxxx> Hi, Marek and Alan I'm a Nvidia engineer and develop this patch file. I used mplayer to test. The channels are mapped good. Running mplayer -ao alsa:device=hw=0.3 6ch.wav I tried to use speaker-test to test, but I can't get the hdmi device name. I used speaker-test -Dsurround51:NVidia -c6, the sound output from the analog jack. Which device name should I use? I use aplay -l, it show **** List of PLAYBACK Hardware Devices **** card 0: NVidia [HDA NVidia], device 0: ALC1200 Analog [ALC1200 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: NVidia [HDA NVidia], device 1: ALC1200 Digital [ALC1200 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: NVidia [HDA NVidia], device 3: NVIDIA HDMI [NVIDIA HDMI] Subdevices: 1/1 Subdevice #0: subdevice #0 Thanks Wei. -----Original Message----- From: Marek Vasut [mailto:marek.vasut@xxxxxxxxx] Sent: Wednesday, June 03, 2009 8:01 AM To: Alan Alan Cc: alsa-devel@xxxxxxxxxxxxxxxx; Wei Ni Subject: Re: ALSA patch Nvidia 8 channel hdmi audio On Wednesday 03 of June 2009 00:30:04 Alan Alan wrote: > Thank's for the info. > How can i contact him ?
