Default Parameters for nvaudio module

Can anyone help? I am successfully running the nvaudio module and do have sound, but I only get it from my front two speakers - not my surround speakers.

The following is the output from dmesg:

Nvidia + AC97 Audio, version 0.24, 03:11:15 Apr 2 2003
Nvaudio: in Funcction Nvaudio_init_module
PCI: Setting latency timer of device 00:06.0 to 64
Nvaudio: NVIDIA nForce2 Audio found at IO 0xb800 and 0xb400, IRQ 5
Nvaudio: Audio Controller supports 6 channels.
NVaudio: Defaulting to base 2 channel mode.
ac97_codec: AC97 Audio codec, id: 0x414c:0x4720 (ALC650)
Nvaudio: only 48Khz playback available.
Nvaudio: AC'97 codec 0, new EID value = 0x05c7
Nvaudio: AC'97 codec 0, DAC map configured, total channels = 6
Nvaudio: PROBE is done

How can I get it from the base 2 channel mode into 4 channel mode?

Thanks

Default nvaudio

Yes, I have same problem - nvaudio is reporting 6 channels, but I never heard sound except for first two reproductors. Google does not give advice howto setup 4,6 channels

Another problem I have is 48khz playing only - some programs complains, that soundcard is unable to play their 44khz sound and does not play anything at all

Post 48Khz Possible solution

Don't know if this will help, but it's from the nVidia website concerning the nForce drivers of which I have one myself :[MSI(NVIDIA) nForce2 Chipset Based K7N2 Motherboard with nVidia AGP GeForce3 Ti200 (128 DDR onboard) ] :................................................. .... nvaudio Module Parameters

The nForce audio driver supports the following optional parameters:

spdif_status
spdif_status
The "spdif_status" module parameter is used to enable or disable S/PDIF support in the driver. By default S/PDIF is enabled, but can be disabled by setting spdif_status to 0. The driver can only support 48kHz sample rate when S/PDIF is enabled, so disabling it will increase compatability with applications that make assumptions about what sample rates the driver supports! Find the nForce Drivers for your Distro here !

Pretty mutch the same output as I get (a7n8x deluxe). Now, your 5.1 surround does probably work, you only need a proper wav-file with > 2 channels or a dvd with 2+3+1 channels and a player that can handle those. So far, the only way I've managed to play a dvd with surround (or .avi with ac3 audio) is using vlc (videolan client). This player let's me select what audio channels/mode I want to play, and it even support S/PDIF pass through. Using "mplayer -channels 6 ..." has the same symptoms as with the alsa-driver. The center channel seems to jump around, from left, to rear and even to the sub, but all channels are there.

Anyone with the same experience? With a possible workaround?
