A question about the audio capabilities of the RV630
Hi everybody, about a week ago i bought a brand new Yamaha RX-V465, so now i have the proper equipment to test not only the simple case of 2 Channel with 48kHz, but also the whole spectrum of the HDMI audio features. The good news is that the standard stuff is working: 2 channels at 32kHz, 44.1kHz and 48kHz. AC3/DTS pass through with 5.1 channels at 44.1/48 kilo bytes per second. The bad news is that i have strong problems getting the more complicated stuff working: More than 2 channels result i a way to fast mplayer and no sound at all. More than 48kHz sampling rate result in no sound at all and the AV-Receiver constantly switching between signal detected/lost. So my questions: Is the RV630 capable of doing high definition audio at all? The specs from ATI are not 100% clear about that. Have anybody of your guys ever got stuff like this working? Maybe with the windows driver? Bye, Christian. -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org

I have also just acquired a surround sound audio processor, so hopefully I can start testing audio too soon on the RV610. I got my experimental system into quite a state so have done an OS reinstall and are rebuilding the xserver at the moment.
More than 2 channels result i a way to fast mplayer and no sound at all.
Sorry, don't understand that. Do you need the -channels 6 (or whatever appropriate number) option? I need that for full mplayer software decoding of 5.1 surround sound for my analogue sound card, but don't need it for hwac3 or hwdts out the digital iec958 port of the sound card. (Haven't yet tried the HDMI out on the RV610 - waiting for that rebuild of the xserver.)

Just to make it clear hwac3 and hwdts work great with the current code, but as i started with the HDMI implementation the ultimate goal was to completely support the given hardware. Multichannel linear PCM could also be quite useful for games or codecs witch are not supported directly in the AV-Receiver, like high bitrate DTS found on blue-ray disk. I just want to know if this is supported in hardware. If not i can stop trying to figure out how to program the hardware.

I don't think there is enough bandwidth for > 2 channel PCM. IIRC, the HDMI spec only allows 2 channel PCM. Alex -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org

Actually, it allows much more: from wikipedia:
HDMI supports up to 8 channels of audio at sample sizes of 16-bit,
20-bit, and 24-bit with sample rates of 32 kHz, 44.1 kHz, 48 kHz, 88.2
kHz, 96 kHz, 176.4 kHz, and 192 kHz. HDMI also supports any
IEC61937-compliant compressed audio stream such as Dolby Digital and
DTS and up to 8 channels of one-bit DSD audio, which is used on Super
Audio CDs, at rates up to 4 times that of Super Audio CD. With version
1.3, HDMI supports lossless compressed audio streams Dolby TrueHD and
DTS-HD Master Audio.
So even HDMI 1.2 supported more than 2 channels PCM.
I have no idea whatsoever whether the RV630 is capable of providing that
bitstream capacity.
