Yep. But rather by coincidence ( at least a quirk to recognize the card and a small routine (usbaudio.c) to handle the samples properly has been implemented). First you need to upgrade the firmware via Windows - which is a must. After that the card defaults to 44,1/16 after power up. This is the reason why 44.1/16 playback works. What's missing, is the complete control of the card modes, register settings etc. If the registers are known, which I assume, according to EMU statement, it shouldn't be a big deal to get it working. Now it would be interesting to know who sits on these information. I'd be happy to get in touch with him to support the design process.

Hi folks.

I learned that EMU handed over specs related to the EMU 0202/0404 USB to you guys some time ago.

Is anybody assigned to the task?

Hi Vedran. How can I get in touch with him? I looked up responsibilities for EMU10k1. Takashi and Jaroslav seem to be in charge for that EMU product. THX Cheers On Fri, Sep 26, 2008 at 5:04 PM, Vedran Miletić <rivanvx@gmail.com> wrote:

James Courtier-Dutton has been making drivers for E-mu PCI cards, so there is a chance that he might be the guy who got the datasheets or know who did. Maybe you should ask him.

James Courtier-Dutton has the E-MU USB specs. Quoting <https://bugtrack.alsa-project.org/wiki/wikka.php?wakka=emu>: "EMU have also now sent me a datasheet for the EMU USB sound cards. I just need the time to play with them a bit to get them working. Please feel free to send me donations to my paypal account: James at superbug dot co dot uk The support for the EMU USB cards has started, and basic support is now in the latest alsa hg. It only supports 48000 rate, but all the in/outs should work. Still TODO: Control of extension units that are used for setting the rate,spdif options etc." That's the last update, from 2007-10-07. Many people have offered help... BTW, I guess the 48000Hz rate refers to the hardware's default sample rate. The E-MU Tracker Pre (and recent 0202/0404 USB firmware) actually defaults to 44100Hz, so it seems only that rate works with ALSA usb-audio. Eran

Hi folks. I'd like to have a look at the subject of developing a driver for the EMU 0404 USB, (at least to see to see how far I can get by myself) I contacted EMU support via Internet - they didn't even answer my question. I am wondering if there is a special channel of how to get in touch with the EMU guys to get the specs and discussing the NDA subject?

Has anyone heard from James recently? I CC'ed him on a question about jack latency on E-mu PCI cards recently, but he never replied. Wonder if he wasn't interested in replying or he is not reachable at all.
