ALSA and external USB Sound Card (UCA222)
« on: September 24, 2010, 08:40:49 PM »
I would like to pass the sound of my notebook digitally (optical) to my hi-fi system.

Now I have the following hardware : UCA222
http://www.behringer.com/EN/Products/UCA222.aspx

The hardware is recognized somehow, but it does not work (no sound) and ALSA plays always on the built-in sound card.

Can someone help me?

Some informations :

dmesg
Code: [Select]

Do the inputs/outputs show up in alsamixer?

Hint:
Code: [Select]
alsamixer -c 0
alsamixer -c 1
to switch between cards.

Also, did you run 'alsaconf' after connecting the USB card?
The '-L' option might be useful.

hi

if you prefer internal not to load.FIRST...you might be better off setting up the internal as index=1 so when you plug in the usb, index=0 is available and is grabbed by the usb device

or if you prefer not to load internal AT all....blacklist its module as per the wiki

Either technique starts the same way with TC 3x series in that you run (with usb device NOT installed)

Code: [Select]
lsmod | grep snd to find out your modules for your internal and add that to your bootloader to blacklist it

b) if you never use internal ....you do no more....and plug in usb and enjoy the benefits

c) otherwise you add some lines to your bootlocal to create index=1 for your internal sound device.

http://wiki.tinycorelinux.com/Setting+up+Sound


2) which alsamixer setting are you referring to you for digital out....spdif ?

Thanks, you guys are great as always!

As expected, it was a hard- and software problem and it sits between my ears ...

After blacklisting all sound modules and loading the UCA222 manually as default (index 0) - I had the sound on the external device (ear phones and optical / spdif).

Meanwhile, I remembered that you can drive the sound devices separately out from mpd :

mpd.conf
Code: [Select]
audio_output {
        type            "alsa"
        name            "My ALSA Device 0"
        device          "hw:0,0"        # optional
...
}

audio_output {
        type            "alsa"
        name            "My ALSA Device 1"
        device          "hw:1,0"        # optional
...
}

Now I have "only" two problems left :

1.) Is it possible to run/configure ALSA in such a way that the sound will always be transmitted on multiple devices at the same time - without consideration of the program (so even if I play a song with vlc or something ...) ?
Currently my ALSA only plays on the default device (index=0).

2.) Currently alsamixer only shows me the mixer controls for PCM, but the device still has a lot more inputs and outputs. I thought I must read and understand the following, but now I am stuck ...
http://www.kernel.org/doc/Documentation/sound/alsa/ALSA-Configuration.txt - paragraph: Module snd-usb-audio

hi

1) since you want 2 devices.....you initially blacklist your internal then re-create it to load with index=1, there is no need to force usb onto index=0.........I have failed to explain that bit to you eh?

Pls post the output of your bootlocal and your grub kernel line bootcode for blacklisting

and post in a code box the command pls.
Code: [Select]
lsmod
EDIT we will need the full list to see the usb stuff.

2) since I lack skills in mpd you may consider this link......tinypoodle or others may be able to mod it so you have
udev rules for usb sound device detected
then piping into both outputs at once.....while it appears to only swap at the moment
https://bbs.archlinux.org/viewtopic.php?pid=334988


3) leaping ahead.....I not sure what your sound module for usb is called

count the number of colour connectors......they are your stacks.

you have a spdif........not sure as I asked but maybe we got confused?.....pls specify if that is to be true output pls....so why the need for others?......I repeat.... which alsamixer setting are you referring to you for digital out....spdif ?

4) it might be useful to post a snapshot of your current alsamixer output screen?

5) it appears you may have only this to play with

Code: [Select]
Module snd-usb-audio
  --------------------

    Module for USB audio and USB MIDI devices.

    vid             - Vendor ID for the device (optional)
    pid             - Product ID for the device (optional)
    nrpacks        - Max. number of packets per URB (default: 8)
    async_unlink    - Use async unlink mode (default: yes)
    device_setup    - Device specific magic number (optional)
                    - Influence depends on the device
                    - Default: 0x0000
    ignore_ctl_error - Ignore any USB-controller regarding mixer
                   interface (default: no)

    This module supports multiple devices, autoprobe and hotplugging.

    NB: nrpacks parameter can be modified dynamically via sysfs.
        Don't put the value over 20.  Changing via sysfs has no sanity
    check.
    NB: async_unlink=0 would cause Oops.  It remains just for
        debugging purpose (if any).
    NB: ignore_ctl_error=1 may help when you get an error at accessing
        the mixer element such as URB error -22.  This happens on some
        buggy USB device or the controller.

so I am guessing we could try....in your bootlocal.....optional add index=0 but I think thats unnecessary

/sbin/modprobe  snd-usb-audio  vid=08bb  pid=2902

TaoTePuh

forgive me for only just looking at maintainer of mpd and in particular
http://distro.ibiblio.org/pub/linux/distributions/tinycorelinux/3.x/tcz/mpd.tcz.info

Playback Support:
                ALSA support ..................enabled
                FIFO support ..................enabled
                HTTP daemon support ...........enabled
                JACK support ..................enabled
                libao support .................enabled
                OSS support ...................enabled
                OS X support ..................disabled
                Pipeline output support .......disabled
                PulseAudio support ............enabled
                Media MVP support .............enabled
                SHOUTcast support .............enabled
                Solaris /dev/audio support ....disabled


2) Do you have any hate of pulseaudio?

If above replies do not generate a working solution for you.....pulseaudio....running as a sound server should be able to stream outputs to both sound devices?

....I am working on a pulseaudio wiki....but I am not overly fond of it....and have limited experience of it

and IMHO....pa is not what defines Tinycore?

EDIT....a wiki now exists

http://wiki.tinycorelinux.com/pa

3) I assume you know there is a forum of MPD?

http://www.musicpd.org/forum/

Alsamixer is not *that* great.
Try aplay -l and -L to see your alsa cards and outputs

aus9, thank you for your efforts!

These are my current settings:

blacklisted modules in menu.lst
Code: [Select]
blacklist=snd_intel8x0 blacklist=snd_intel8x0m blacklist=snd_usb_audio

I start the devices like this - later I put it into the file boolocal.sh
Code: [Select]
sudo /sbin/modprobe snd_usb_audio ignore_ctl_error vid=0x08bb  pid=0x2902 index=0
sudo /sbin/modprobe snd_intel8x0  index=1
sudo /sbin/modprobe snd_intel8x0m index=2
sudo /sbin/modprobe snd_mixer_oss
sudo /sbin/modprobe snd_seq
sudo /sbin/modprobe snd-pcm-oss
sudo /sbin/modprobe snd_seq_midi_event
sudo /sbin/modprobe snd-seq-oss
sudo /sbin/modprobe snd_page_alloc

sudo /usr/local/etc/init.d/alsasound start

If done like that, I get sound on the UCA222 (ear phones and spdif).

count the number of colour connectors......they are your stacks.

I did not understand. I have 2x cinch in, 2x cinch out, 1x earphone and 1x optical spdif at the UCA222. What do you mean by "stacks"?

Quote
you have a spdif........not sure as I asked but maybe we got confused?.....pls specify if that is to be true output pls....so why the need for others?......

My notebook has no spdif. My notebook only has an earphone output. So I got the UCA222.

Quote
......I repeat.... which alsamixer setting are you referring to you for digital out....spdif ?

I do not know exactly what you mean by "alsamixer setting". If I load the modules as decribed above, I get one controller (PCM) in alsamixer. This controller controls the volume of the earphone output on the UCA222. Unfortunately I have no controller for spdif.

Quote
4) it might be useful to post a snapshot of your current alsamixer output screen?

2) Do you have any hate of pulseaudio?

No, no hate but no experience. At first I wanted to know if I can do this (multiple outputs at the same time) directly with alsa.

EDIT....a wiki now exists

Thanks! I will now try pulseaudio.

hi

firstly you have one internal device ...yes? and it needs 2 intel modules so your sudo can change to

 
Code: [Select]
sudo /sbin/modprobe snd_usb_audio ignore_ctl_error=1 vid=0x08bb  pid=0x2902 index=0
sudo /sbin/modprobe snd_intel8x0m  index=1

Now either that will enable the other intel module you replace with the other line but if you have only one sound device you can't give the modules different indexs....so you have 0 or 1 not 0 + 1 + 2

The reason I think its snd_intel8x0m....is because your ac97 depends on snd_intel8x0m mentioned first and then the other one

2) pls do not include all the other modprobes....they will load automatically.

try it and report back if any probs

3) Have you tried the line with  ignore_ctl_error=1?

or without any mention?

I don't think it will work with no =0 or 1 against it.

4) hiro.....you are right...............aplay -L and -l are in the setting up sound wiki so TaoTePuh.....check your lsmod to confirm you need less modprobe lines ...........then post the output of the wiki commands for aplay pls

5) colour connectors and spdif .....I am referring to your usb device not your internal device.

Each colour connector has a colour for us simple folk......

Your link did not show those colours but did say it had a spdif ok?

so describe them pls

6) Your goal..............with alsamixer......sorry hiro...........is to show a mixer setting for your spdif

that means I suggest you do not load any intel modules but try a number of permutations for your usb sound module with or without
ignore_ctl_error=1 or ignore_ctl_error=0 or not mentioned until we get that mixer setting pls

good luck

there is also the  device_setup that can be added to modprobe but I have no experience as I have no usb devices so not sure if you input a PID or a location reference

hi

and revisting this parameter

Code: [Select]
ignore_ctl_error - Ignore any USB-controller regarding mixer
                   interface (default: no)

so if you do not have it in your modprobe (manually or bootlocal) the default behaviour is to be no.....buts it contra-positive ....meaning if we used

ignore_ctl_error=1 (meaning yes) or  ignore_ctl_error=yes

then we won't get access to the mixer settings that the usb may be attempting to supply.

so thats not what we want .

therefore leave this parameter not mentioned in your  modprobe command.

sudo /sbin/modprobe snd_usb_audio vid=0x08bb  pid=0x2902

No, I think there are two devices. One is for the modem "snd_intel8x0m" (m=modem ???).

You're right, it's possible without. When I have tested 3 days ago, I could not start alsa.

I have tested without success.

Sorry, but I still do not understand. The Box has 2 white connectors and 2 red connectors. Perhaps the following pictures helps:

Yes, I have tested all versions. But I get only one controller (PCM) in alsamixer (see picture above).
