Problem with M2Tech Hiface 2 and Vortexbox Player

[sridhar]

I am trying to set up an M2Tech Hiface 2 USB to SPDIF converter with Vortexbox player.
I am running v. 2 still. The device is recognized properly, but 96Khz files are being played
at half the frequency (and so are 88.2 Khz files).

Here's the info from ALSA:

ALSA device list
0 [M20 ]: USB-Audio - M2Tech USB Audio 2.0
M2Tech M2Tech USB Audio 2.0 at usb-0000:00:12.2-3, high speed

List of audio device ports
1: : sequencer
2: [ 0- 0]: digital audio playback
3: [ 0] : control
33: : timer


Also, here's the output while playing a 96khz file:

cat card0/stream0

Playback:

Finally, here's the output of aplay -L:

Any help would be most appreciated!

What did you put for the device in the Configure Vortexbox Player GUI page?

[sridhar]

I left it at Default. Is this incorrect?

Try plughw:0,0 or plughw:1,0 depending what number the device is in the list..

Great, plughw:0,0 did the trick! Output below when playing a 24-bit 96khz file:

Oops, spoke too soon! The frequency is now correct, but I am getting no audio sound.

Any suggestions on what I should be checking? The volume on the Vortex Box player is set to maximum.

[sridhar]

Here's some useful info from dmesg. Does this mean ALSA mixer is unable to set the volume, and thus I am getting no sound?

OK, I got it working fine! Output was muted in ALSAmixer.

Thanks, everyone....

Please add M2Tech Hiface 2 in the list of properly supported USB devices for Vortexbox 2.1.

[sonorejr]

sridhar, can you post the output of this command? It assumes that your Hiface 2 is hardware 1..
amixer -c 1

The device number in my case is 0. Here is the output of amixer -c 0:
