Fw: Re: Echo Audio Indigo Generic Driver

[Yon Mercury]

Dear ALSA-listers:

This from Echo Audio, in response to my inquiry about an Indigo IO driver:

I hope we can get a good low-end low latency laptop solution soon-- those RME
boards are expensive!

We are aware and have been allowing the linux community to use our SDK.

The indigo one is delayed because we've been working on other projects.  It 
will be released, I'm not sure when our developers are very busy.

I'm the one who developed the ALSA driver. Echoaudio told me
that dev infos required for Indigo support will be released
soon. But there is another problem: those infos are not enough.
My driver already supports all other PCMCIA cards, but none
of the people who tried it was able to make it work. The
problem lies in the CARDBUS bridge and reading the archives of
this ML I found that some people had troubles with RME cards,
too. An Echoaudio developer confirmed that he had to tweak the
registers of the bridge of one laptop to make it work. The
problem is complicated by the fact that there are several tens
of bridge chips around (read: different laptop --> different
fix) and all I get from the DSP is "init OK" or "init failed".
I have no idea of what the problem is. Suggestions are welcome.

Hi Giuliano,

Oh good, I'm glad I got your attention. I'm not fluent in the CARDBUS
architecture. How does Echo handle this multiple bridge issue in Windows? Or
is it handled by a separate bridge driver? If so, perhaps we need to add
another layer to the ALSA architecture to handle different bridges. 

I think that cardbus components not specific to the Echo Audio card should be
handled by another team. I'm more an applications developer, but I'll support
you in whatever way I can.

Me too.

Who knows ?

No, what a mess. I think someone with one of those cards should
contact the team who maintains the driver of his bridge and look
for a solution.
