Unable to get upmixing to work with USB 5.1 sound card

Hello!
I'm having some trouble with an USB 7.1 sound-card that I want to use for my 5.1 sound system.
The sound-card is connected to my Lenovo Thinkpad T400 via docking staton on USB.

all speakers make a noise when they are shown during the test correctly.
In the wiki, I tried some examples on the configuration of ~/.asoundrc as described, but none of them worked - everything I specify there is effectles, even after reboot.

type upmix
slave.pcm "surround51"

So what am I doing wrong?

Hello there!
In the german forum, I found some more help.
This configuration now got 5.1 sound mixing to work via ALSA (without using PulseAudio).

Any ideas?

Arch and Tascam US-122L USB 2.0 Sound Card

Hello,
I recently tried using my Tascam US-122L sound card, but I am not aware if there is support on linux for it or not. I tried the AUR, but it gave me information about a different Tascam card. I found this website which is interesting but must be outdated:
http://www.pps.jussieu.fr/~smimram/tascam/
I did a simple lsusb and the card seems to be recognised correctly by the system:
Bus 002 Device 007: ID 0644:800e TEAC Corp. TASCAM US-122L
but alsamixer gives me the message:
"This sound device does not have any controls."
and the device is not chosen (sound is coming out of the original speakers instead of the US-122L Phones output).
Maybe I am just failing to switch to the card? Any help would be appreciated.
Thanks in advance,
silentz0r

This soundcard is supposed to work ootb, there's a kernel module just for this card.

The controls (e.g. volume etc.) are hardware controls, so there's nothing to be done for the software. That's why alsamixer shows this message. In order to get any sound, you have to either configure this soundcard to be the default one(*), or you have to tell the player to use this soundcard(**).
(*) There is a gui which can do this for you quite easily, it's called asoundconf, you can find it in the AUR.
(**) You can do this e.g. with mplayer like this
mplayer file.end -ao alsa:device=plughw=2.0

Does the iMac support a USB-5.1 sound card?

I have a new Intel iMac connected though USB to a "Sound Blaster Live 24 bit" sound card connected via mini-jacks to a logitech 5400, but I am not getting 5.1.
In the Audio MIDI pref pane, I can only select "multichannel," not "5.1".
Is there any way to fix this? If not, I need an optical to mini jack... any idea if there is such a thing?
Matthew

Hi Matthew,
I don't know about the SBlive 24bit device.
However, the Intel iMac's all have built in 5.1 optical output from the normal headphone jack (it is optical and electrical). There exist TOSLink to 3.5mm optical cables, and some can even be converted to either.
There are also some optical to coax SPDIF converters available if your speakers only take SPDIF coax and not SPDIF optical.

Usb Sound Card Playback Issues - Alsa [SOLVED]

Hey folks:)
Just want to say Archlinux is lovely and you guys are doing great work (if be it a little frustrating at times i might add)
My problem is that i can't configure my USB UA-25 sound card properly.
If i want to record with ardour, or hydrogen using JACK, everything is fine.
BUT.
If i want to play back a simple music file, or run 'youtube' for example, sound refuses to come out of my computer.
In system>preferences>sound the driver is set to ALSA.
How can i get sound to play back normaly through my externel sound card? I think Archlinux is trying to use my onboard laptop sound card.
Thanks!

fixed the probelm;
Had to reinstall alsa dirvers, removed all instances of 'usbaudio' from the modules. Reboot. modprobe snd-usb-audio. unmuted all mixers.
Selected alsa as the driver. Test. Yay! :"")

How to connect my iphone 4s to a USB sound card for 5.1 speakers?

How to connect my iphone 4s to a USB sound card for 5.1 speakers?

You can't:
1. iPhone sound output is stereo, not Dolby 5.1 compatible.
2. iPhones do not connect sound output by standard USB. The connecting device has to be iPhone compatible.

Can I connect a USB 2 sound card to a Macbook equipped only with USB 3 ports?

Hello,
I just learned I might have to purchase a new Macbook because my USB ports are fried and I was looking at purchasing a refurbished Macbook pro from 2012:
http://store.apple.com/ca/product/FD101LL/A/refurbished-133-inch-macBook-pro-25g hz-dual-core-intel-i5
the only trouble is I make music with a MOTU Audio Express sound card, and it only has a USB 2 port and a bus-powered Firewire (which I don't like using since it hasn't been too reliable in the past).
http://www.motu.com/products/motuaudio/audio-express/summary.html
Unfortunately, it seems that the Macbook I'm looking into purchasing only has USB 3 ports, and I looked for info on USB 3->USB 2 adapters online and this simply doesn't seem to exist. The only info I managed to find on this subject was this little bit on the Apple website:
Can a USB 2 cable be used to connect a USB 3 device to my computer?
If the device end of the cable fits into the connector on the device, yes. However, because it has fewer wires, you won't get USB 3 speed and power may be limited to 500 mA.
does this mean that I can connect a USB 2 cable from the USB 2 port of the MOTU sound card to the USB 3 port on the Macbook? I'm OK with the power and the speed being limited to USB 2 power, I just want to make sure I can actually use my sound card with this new Macbook.
Thanks!

I think I'm understanding this a bit more now.
Here is the cable that I use:
http://www.amazon.ca/USB-Cable-Type-Male-Black/dp/B00183I7EE
The Type A part is the one that I'm currently putting into the Macbook and the Type B part goes in the sound card.
Would this work with a USB 3.0 port on the Macbook?
Thanks for your time and patience...

[SOLVED] USB Sound card no longer working

I have used a Focusrite Scarlett 2i2, a USB audio interface, as my default sound card for the last two months or so. Its output comprises two RCA jacks. I have a cable that is two RCA male leads on one end and an 1/8" on the other. I use this cable all over the house, so I unplug it often. The USB device remains connected. Last night, while plugging the cable back into the device, I jostled the USB and the device lost power momentarily. Since then, ALSA has not been able to "see" the device. The device is, and always has been, plugged into a D-Link USB hub, which goes into the computer.
I did pacman -Syu and rebooted to no avail.
uname -r

The first line I recently commented out as an experiment. If this line is left in, ALSA attempts to use snd_usb_audio and when I run alsamixer it complains that it can't find the device. If this line is commented out, ALSA ends up using the on-board sound. Particularly, it uses 'HDA ATI HDMI'. There are two choices: HDA ATI HDMI and HDA ATI SB. When I was using the on-board sound, I was using HDA ATI SB.

This is painfully true. This morning, I realized I didn't even check the D-Link. The LEDs on the interface were lit up from the USB connection, but the AC adapter was faulty. I replaced that, restored my original configuration by removing the # from the first line of my alsa-base.conf, and now everything is working again. The D-Link was simply unable to provide the device with enough power to operate.

External USB Sound Card and 6-channel 5.1 SS speakers not working

Hi. I purchased a few devices to expand my sound to 5.1 surround sound. However, I'm having trouble getting any results at all. Here's my situation.
New 24-in Intel iMac
Logitech G51 Surround Sound Speakers
PPA International External Sound 6 Channel USB device
I can select the audio device in the Sound control panel and under the Audio MIDI Setup utility. I have changed the device to be a 6 channel device, but I cannot get any sound to come out of the speakers at all. It could be that this particular USB audio device is not compatible, but since it shows up as a selectable device I had some hope that it would work. The device doesn't claim to be mac compatible, but that isn't always a requirement. I crossed my fingers and took a chance.
If anyone has any suggestions I would appreciate the help.

I'm almost certain it is because of the lack of a mac driver for this particular sound card. <gasp> This setup works great under XP when using BootCamp. If I'm dead in the water with sound card, are there reliable alternatives I look for?
Here are the links to the products I'm referring to.
The sound card:

External usb sound card is not working correctly

When my computer usb sound card is working correctly. If your computer to sleep and wake up the sound card is working correctly. If you disable the sound card and connect again, it appears extraneous sound on the background music playing. Each time the sound is different. The sound is very similar to not match the sampling frequency. If the computer is rebooted, then the sound card is working properly again.
Soundcard Infra-sonic.com model Amon.
I have not experienced problems when using the same card with Mac OS 10.5.8 with the drivers for Mac OS 10.5
Manufacturer issued driver for Snow Leopard, but the card still does not work correctly.
Also such problems, other users complain about an external USB audio card. None of the users can not find a solution to this problem.

Suggest me a usb sound card for mac mini

please suggest me a usb sound card for mac mini (i need 5.1 sound)

The Griffin Technology FireWave will give you the 3 'cables' ("FireWave outputs six channel audio through three 1/8” (3.5mm) stereo mini-jacks: Left/Right, Center/Subwoofer and Right Surround/Left Surround.") connection for surround sound (speakers) audio. Whether or not a particular headphone set is compatible, you might ask Griffin directly about that. If you're playing a DVD with VLC or the Apple DVD Player, you will get surround sound. But, you'd have to find an MP3 with multi-channel audio inside it to play surround sound out of iTunes.

External USB Sound Cards

Hello! Im thinking of switching to a mac but one thing stumps me - would i be able to use an external sound card (creative sound blaster x fi, USB based)
From what it seems, Creative does not directly support the operating system but was wondering if the Mac OS drivers can at least "map" the 5 channels to work.
Since it would be nice if i can continue to use the 5.1 surround speakers to their potential - thanks for any help!

Whenever you're playing a source that provides 5.1-channel audio, the MBP's digital optical audio output is also 5.1.

Two simultaneous sound outputs by using external USB sound card

Hi
I have a MacBook Pro running Mac OS X 10.4.1
I've also bought a Griffin iMic as my second sound card.
Mac OS X shows my internal sound card as well as the external USB one and I can
easily switch between them. I was wondering if there is a way of using both at the same time, say, the internal speakers play song X and the headphone connected to iMic play sound Y.
Do I need a special software for this ?
Is iTunes capable of doing this ?
Any input is appreciated.
thanks
Ahoora

hi i just like to say i had a similar fault though i would be surprised if it causing yours,but you never know,my fault was my laptop lid, [9 months old] it contains the mic ,and when the lid was in a certain angle crackles could be heard worse when i had my external sound card in, it was a faulty membrane [ lid to body] easily missed by engineer because it was the same angle all the time it happened,good luck, PS you English is very good

[SOLVED] Audio dropouts with USB sound card

Hi! Recently I bought an external USB sound card (Music Fidelity V-DAC). If I plug in the USB cable the sound device is recognized by Phonon in KDE4 (kdemod).
If I play an audio file in Amarok (or VLC) the audio is indeed redirected to the USB sound card and played correctly. However, if I use my USB mouse, or USB keyboard dropouts are occurring in the audio signal. It seems that other USB devices are interfering with my USB sound card.
More details:
Arch Linux with kernel 2.6.33 and kdemod 4. Phonon backend is Xine. I also tried gstreamer, but this crashes Amarok/

I also tried an Ubuntu (9.10) live CD. Using ALSA or Pulseaudio a clean audio signal without dropouts is produced.
I wonder if someone can help me with this problem, or point me to more information. Thanks!

Thanks for your suggestion. I added the following line to my /etc/modprobe.d/modprobe.conf file:
options snd-usb-audio enable_msi=1
After a reboot the problem still persists. I also tried another suggestion from this forum:
options snd-usb-audio nrpacks=1
This doesn't work either. I tried to change settings in /etc/security/limits.conf, which looks like this:
@audio - rtprio 99
@audio - nice -10
@audio - memlock 250000
The USB sound card doesn't share a IRQ with another USB devices, as can be seen here:

Any other suggestions?
I even tried to disable the internal sound card by blacklisting it:
blacklist snd-hda-intel
.. but still no success

USB Sound Card usb_set_interface failed

Hi all,
My sound seems to work for a while (pure ALSA at the moment, though I've had the same error using pulse too), then an event (mostly pause) seems to cause sound to stop working without a reboot. Here's the relevant information:
lsusb
Bus 003 Device 002: ID 08bb:2706 Texas Instruments Japan
aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: DAC [USB Audio DAC], device 0: USB Audio [USB Audio]

From then on the device is not listed under aplay-l until the PC is restarted.
This has been driving me nuts for a while now, and I can't find a solution. Does anyone have any suggestions?
Thanks in advance for your help!

Google is your friend. I cant recommend one directly because i dont have one, but using this search term "USB Sound Card mac" a whole host of stuff comes up. YMMV: http://www.google.com/search?hl=en&client=safari&rls=en-us&q=USBSound+Cardmac&btnG=Search
I would however suggest investing a reasonable sum of cash in an external sound-card in order to make sure it is an "upgrade"
