Summary:                    Request: please enable 44.1khz playback on Audigy 2
NX
Description: 
It saw somewhere in the changelog that 44.1khz playback on Audigy 2 NX is
buggy so it is disabled in the latest source. However it seems that
44.1khz playback in digital-output-only mode is working perfectly.

I have used a Audigy 2 NX to send 44.1khz signal to external DAC for
several month in my home theater setup (with kernel 2.6.12.x). The driver
has been rock solid (thank you guys!). Although I do need to set the
output frequency to 44.1khz using a Windows laptop, that is necessary only
after the sound card lost its power, i.e. unplugging the power adapter. 

In kernel 2.6.13 or the latest alsa-driver, 44.1khz playback is disabled.
I'd like to know if it is possible to re-enable it? It is a nice feature
that the hardware is capable and the driver is available. Maybe something
similar to Windows can be done: user must select digital-only mode before
44.1khz output becomes an option; once in digital-only mode, all analog
channels are muted. 

What do you think? Maybe the output frequency can be fixed by user intead
of by the music source being played. Is it hard to implement?

The problem is that I haven't been able to reproduce the command(s) that
the device needs to go into digital-only mode.  I'll have to do more
reverse engineering ...

Was this resolved in later ALSA releases?
