[Alsa-user] CREATIVE EMU 0202 driver in 192khz

2016-11-02 Thread Olivier Schmitt 
Hello,

I am SCHMITT Olivier and I am IT manager for a Radio Ham Club.

Let me explain quickly, I search to use ADC (line in) from an Creative
Creative EMU 0202 in 192K but it was detected by alsa on 48k sample rate
only.


I have a computer that I need to update. It runs on 32-bit version 17
LinuxMint (it seems to be the version of ubuntu 14).
The card works in EMU0202 192k on this machine before.

I test all 32 and 64 bit version of Ubuntu Ubuntu 12.04 to Ubuntu 16.04 and
LinuxMint 13 to 18 and this card was only detected on 48k max and not
192k... USB2.0 for sure!


Here is the extract from alsa Repport:

How I did you observe that?

I use the utility "alsacap" to see all the features available.
I also use to arecord verified the information.
I can only use 48kHz bandwidth under the new installation of Ubuntu.

The old person now deceased was installed on LinuxMint and we could use in
192khz. But I do not know how. he probably made the snd-usb-audio driver
with a patch. But I'm not sure. It seems this is the only lead I have.

This seems normal because in compatible sound card matrix of ALSA-project
website, it seems that the driver by alsa only allows maximum 48khz.

I would like to have your opinion to perhaps find a suitable track.

If you see this return of alsacap utility, you see that in the older
computer this will allow to use this sound card under 192khz.

I test every version of linux mint from the 13 to the 18 and Ubuntu 12.04 to
16.06 (32 and 64 bit) and they are all the card 48khz.
Also, I try to make the latest version of ALSA driver without success.

Alsacap return:

[Alsa-user] Stream capture of S24_3LE mostly null from USB

2016-11-02 Thread Barry Neilsen 
I'm a beta tester for a synth trying to troubleshoot a new Class Compliant
USB IO board. It uses UAC2 to stream 192k stereo, or 12 channels at 48k or
96k. The snd-usb-audio module loads when I connect the device and it looks
to be identified correctly under /proc/asound, reporting its output format
as S24_3LE, which I believe is correct.

With one exception, though, any stream I capture from this input - I used
arecord, Audacity and Jack (via alsa_in and routed to my soundcard output)
- contains mostly nulls with what looks like the occasional valid data
point, every hundred or so samples. (I haven't counted them.)

The exception is Ardour using the ALSA, which captures the entire 12
channel stream flawlessly.

What might Ardour be doing to set things up properly and how do I replicate
this such that the rest of my system does it, too?

(I'm running Ubuntu Studio 16.04.1 LTS with ALSA Version k4.4.0-45 on a
Thinkpad X230.)

Thanks
