Thanks, but didn't help my problem.

I think this is not Total Mix's Problem, but the RME driver or Windows' one.

Thanks,

Sorry, I forgot writing about playback software.
This problem occurs when I use WDM multi-channel (more than 3) audio, not ASIO.
(Perfect on ASIO, I think. :-) )

- Some games, for example Age of Empire II Forgotten Empire, recent games also
- Power DVD 4ch, other DVD software also
- Sound Forge WDM, other sonic foundry lines also

I also tried this way ( change the number of WDM devices )

Driver version 1.114
Firmware 357

Regards,

I updated the driver from 1.114 to 1.164. Thanks.

Then, it does worse behavior. :-P I think this did not happen when I use older drivers than 1.114. (I don't remember the previous driver version, caz I really trust RME :-) )

When I select "Speaker: RME Fireface UFX"(Analog 1+2) for the default on Windows' Sound Control Panel, (for example) Winamp WDM don't playback anything on every sampling rate except 44.1k. When I select "Analog (5+6)" for the default,  it works on any sampling rate.

Of course I checked the property of the device, and the driver returns these wrong formats listed below for the Analog 1+2 on the Speaker Property [Detail] tab. There are some other selectable formats in drop down list on some sampling rates, but it doesn't work.

(24bit)
(Fireface USB Settings > Returned Formats on Speaker Property [Detail] tab for Analog 1+2)
32k > 88.2k
44.1k > 44.1k correct!
48k > 44.1k
64k > 48k
88.2k > 48k
96k > 88.2k
128k > 96k
176k > 128k
192k > 176k

Regards,

Sounds like fully normal behaviour. WDM can not change the sample rate of the hardware. And if you can stlil play then the WDM kMixer is doing sample rate conversion to the current base rate (easy to see, check the Settings dialog).

You seem to have not checked Speaker format setting (like Stereo), sometimes this needs to be reset. And what happened to your 'channel 3 playback' problem?

Now I understand the problem, and I could reproduce it. We will fix this.

Once you toggle the sample rate back to 44.1 and then to 48 again the playback will work. This seems to be an installation initialization problem. If setting sr forth and back does not work unplug the UFX, reboot the computer, replug the UFX.

On a clean installation it works, there must be a different error then (USB drivers not up to date or similar).

We examined this issue more and found that it is a registry problem. Under Windows 7 one has to deinstall the RME device in the Device Manager, make sure that 'remove software/drivers' is checked as well. On reboot Windows will install the former driver (if there was any), so the procedure has to be repeated until no driver, or driver 1.099 is active. Then an update to 1.164 results in error free WDM operation.

We are currently preparing driver 1.165 which does not cause that registry hickup, but the procedure described will be necessary as well (then even under Windows 10). There is no other way to remove the registry data of all devices and sample rates.

Or please tell me the Keys location where the FireFace Driver Settings stored in Registry.
I'll remove it.

Edit: Link from test driver removed

For this to work differently you most probably need a clean installation base, again.
