Hello,

I've sent this email to Clemens Ladisch, that appears as the developer
of the snd-oxygen driver, but just in case he is not the actual
maintainer of the driver, I'm forwarding it here.

Thanks,

Hello,

I've read in the alsa-users mailing-list
(https://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg29284.html)
that there is no support for the HT Omega Claro II card and that you
should have to reverse engineer the windows driver to add it. I have
that soundcard, although I has been able to use the onboard HDA audio
when booting to Linux. But now my onboard audio is not working (it is
dead, not working either under Windows) so I'm trying to make the Claro
II working under Linux. I've contacted the HT Omega support and to my
surprise they actually answered with some useful information. I've
attached the email. The summary is that the Claro II should be exactly
the same as the other cards by HT Omega using the CMI8788 except that
the GPIO for initializing the card is #6.

I have compared specs for both Claro (http://www.htomega.com/claro.html)
and Claro II (http://www.htomega.com/claro2.html), and there are more
differences, the Claro uses AK4396VF and WM8785G chips while the Claro
II uses AK4396VF and CS4362 (+ CS5361 for line input). I've checked the
code under sound/pci/oxygen and it seems that we have support for the
CS4362 for the Xonar D1/DX soundcard. I don't know if having the GPIO
pin for initialization and all the other chips already there is enough
to add support, of course I'm willing to test any patch that you could
provide. I've taken a look at the code, as I'm not bad with C, but audio
driver development is completely outside my skills and domain, so I'm
quite lost, if you don't have time or if it is not trivial to add
support for the Claro II I would understand it, but the card is a really
good one and it is quite easy to find in the US, it would be awesome to
have support for it in ALSA.

Thank you for your time!

Dear German Gomez

I'm sorry for this issue. 

8788 has no official driver for Linux. This is Cmedia policy.  And we have no information about driver side. 
Cmedia doesn't share about driver information with any hardware manufactories.  
Thank you for your understanding.  

But there is one information. If the other 8788 cards are working properly, Claro II isn't different except GPIO initializing.  
Claro II uses GPIO #6 for initializing.  But we don't know how it is working.  I think the developer has some idea. 

By the way, we still recommend Windows system for using full feature of Claro II. 
Feel free to contact me with any question.

Thank you.
Sincerely,
Jason.
HT OMEGA

Subject: HT Omega Claro II Linux support

Hello,

I'm trying to use the HT Omega Claro II under Linux (Ubuntu 16.04), but I've found that it is one of the few cards from HT Omega that is not supported by the Linux Sound System, ALSA (http://www.alsa-project.org/main/index.php/Matrix:Vendor-HT_Omega).

According to the developer of the CMI8788 driver it seems that the information to support it is not available:

https://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg29284.html

Is there anyway to provide that information to the developer, so he would be able to add support to this awesome card to Linux? As I was searching for a solution, I've found that there are many other users like me looking for support under Linux.

Thanks!
