I get the following OOPS when loading the snd-ice1724 module for my Envy 24HT card. Works fine if I build all the alsa code straight into the kernel.

Yes, the module loads fine now.
I have a couple of questions regarding this card (M-Audio Revolution 7.1) and ALSA if you'll humour me.
A) Does the driver support more than 2 channels of sound? I've had no luck getting output out of anything but the analog front channel.
B) Instead of the typical <Master> <PCM> <Line> etc channels in alsamixer I have DAC[1-7], with the front left & right channel being <DAC> and <DAC1>. Is this normal?
C) mplayer (http://www.mplayerhq.hu) compiled with alsa support will detect the card but fails a snd_pcm_hw_params_set_format call. It will work fine via OSS emulation however. The same build of mplayer works fine via alsa with other cards, tho. Is this a driver problem, a hardware limitation, or a problem in mplayer?
Thanks.

yes. you'll need to raise the DAC volumes.

what program did you use?
if you want to duplicate signals to surround ,etc., you can configure
it in your ~/.asoundrc file. (only for ALSA apps, though.)
we don't do signal duplication in kernel.
> B) Instead of the typical <Master> <PCM> <Line> etc channels in alsamixer I have DAC[1-7], with the front left & right channel being <DAC> and <DAC1>. Is this normal?
yes. it's not a typical consumer card.
if you have 6 or 8 channels, which should be called "Master"? :)
> C) mplayer (http://www.mplayerhq.hu) compiled with alsa support will detect the card but fails a snd_pcm_hw_params_set_format call. It will work fine via OSS emulation however. The same build of mplayer works fine via alsa with other cards, tho. Is this a driver problem, a hardware limitation, or a problem in mplayer?
the problem of application. the application should use plug (or
other) plugin to convert the sample format on user-space.
