support for usb soundcards

[rperre]

what version of squeezeslave are you using?

squeezeslave -V (or v) will tell you

If you have anything prior to 155 it did not show the usb device for me either, after compiling the new one it did show.
ralphy who is handling squeezeslave is up to 173 now and the latest addition he has added is the ability to set latency from command line with -y.

totallymaxed, do you all use the latest version or an older version with 0710? also do you all alsa or oss?

I have that exact same USB audio card from startech, just rebranded, i have to look at it again when i'm back home.

My list with Cmedia USB device is:



lsusb:

Code Select Expand

Bus 003 Device 002: ID 0c76:160b JMTek, LLC.

squeezeslave -L

Code Select Expand

  0: SB Live! Value [CT4832]: ADC Capture/Standard PCM Playback (hw:0,0)
  2: SB Live! Value [CT4832]: Multichannel Capture/PT Playback (hw:0,2)
  3: SB Live! Value [CT4832]: Multichannel Playback (hw:0,3)
  4: USB Audio Device: USB Audio (hw:1,0)
  5: front
  6: rear
  7: center_lfe
  8: surround40
  9: surround41
10: surround50
11: surround51
12: iec958
13: spdif
14: spdif_playback
15: asym_spdif
17: asym_analog
18: dmix
*19: default

so you can see even this very cheap simple usb audio card is showing up as 4.

Hi,

counld it be a problem when I already use a pci Soundcard?
02:09.0 Multimedia audio controller: Ensoniq ES1371 [AudioPCI-97] (rev 06)

The USB Soundcard would be the second Soundcard to do things like this:

I don't hope so..

[rperre]

your pci should not be a problem, indeed the usb should show up as the 2nd card.

what does aplay -L tell you?

and again what version of squeezeslave are you using?

Your USB audio card is not recognized by the system, so squeezeslave will not see it either.

You can see that my USB Audio Device is showing in aplay and i also have a pci card in my core. Not sure why yours doesn't because it shows in lsusb. you have to look in dmesg or something to make sure the drivers get loaded.

You do have the latest version of squeezeslave, so that should not be the problem.

Hi,

I have seen that the USB audio card is not recognized by the system. But why is the card not recognized? Today I did a apt-get upgrade. A lot of packages where upgraded but the USB audio card is still not recognized...

Regards

[rperre]

I came home today and i actually have the exact same sound card as you posted above. it get's detected in my system.

Can you see in dmesg if your driver is loaded?

sound plays through this usb adapter without problem, just can't get squeezeslave to behave with it.

Bongowonge what version of alsa are you running now?

Richard

[bongowongo]

1.0.17
I have made a ticket with a possible solution, just some information I found on the net.
It has something to do that on specific kernels you need to compile with different flags enabled to prevent this from happening
