[alsa-devel] Creative X-Fi Titanium HD ctxfi bugs 5378 5218 4868
Hello folks,
I bought an X-Fi Titanium HD thinking it would work with the ctxfi driver but it is a new card and has a few differences from the earlier cards. Creative technical support have been quite helpful in answering my questions. This email is a heads-up to let you know that I'm doing some work on the driver.
I'm not finished yet. In particular the PLL initialization still does not work reliably, the capture source selection is a bit broken and one of the ADC chips is being driven out-of-spec when the card is run at 192kHz.
I have attached the current state of my changes which are enough to get the Titanium HD card working but the patch shouldn't be applied because my hack at the PLL code and a couple of other bits may break existing cards. I have been working against the ALSA 1.0.24 release so this is a patch against 1.0.24.
I'm waiting for creative to answer my questions about the PLL initialization and correct setup for 196kHz operation. Once I get the answers I'll try to fix the issues and submit a cleaner patch.
Comments on the current version are welcome.
Harry

Thanks for your work. It's good to know that the model actually works somehow indeed.
A few comment about the patch:
- Instead of adding have_dedicated_mic and have_output_switch callbacks in every place, I'd put some bit flags indicating the capabilities, and set at the initialization appropriately. - A few easy coding-style issues; run scripts/checkpatch.pl and fix the errors appropriately.
thanks,
Takashi
Hi,
(2nd attempt at this email as the first went over alsa-devel's 60KB limit)
I have redone the patch against today's git repositories. Creative have not yet got back to me about the PLL initialization. Perhaps we can fix that later.
I have only put the PCI ID in the pci_ids_compat.h.in file. Is it going to be necessary to add the PCI device ID somewhere in the kernel tree to avoid breaking the kernel build?
A few comment about the patch:
- Instead of adding have_dedicated_mic and have_output_switch
callbacks in every place, I'd put some bit flags indicating the capabilities, and set at the initialization appropriately.
I will follow up with a second patch.
- A few easy coding-style issues; run scripts/checkpatch.pl and fix
the errors appropriately.
checkpatch now reports no errors.
I've only tested these changes with my Titanium HD card. I don't have any of the other X-Fi cards so I couldn't do any regression testing.
If there's anything else I need to do, please let me know.
Thanks,
Harry

Here's the second patch.

Hello, I just want to confirm that the patches you have submitted are working for me under Fedora 15 64 bit. Thank you very much for attacking this issue; my music sounds great so far with this driver in conjunction with the Titanium HD card. Please let me know if you would like me to test any additional changes you may make with any future patches. Thanks again.
