[SOLVED] USB sound broblem.

Greetings everyone. Kinda sucks making my first post on new boards this way.
Can't say I am very experienced linux-wise, but until now I successfully overcame all problems I've encountered. On this one I can't even think where to start, because all this kernel stuff is kinda complicated to me yet.
After initial install all hardware were detected and working well. During days of polishing system I lost track of changes and can't really say what triggered my USB sound card disappearance. At first I was blaming ALSA, but then I checked kernel.log:

As you can see: there is no usb 6-1 "After". Let ALSA messing alone (because it seems unrelated) so far I tried:
- different USB ports
- reinstalling kernel
Any tips or solutions are welcome.

After reinstalling udev, I atleast started to getting following things:

I tried echo -1 >/sys/module/usbcore/parameters/autosuspend as somewhere suggested, but didn't help a bit.
There is also solution to disable USB 2.0 via modprobe -r ehci_hcd, but I cannot allow that because through this device I stream much bigger bandwidth, than USB1.0/1.1 can handle.
EDIT:
- tried to remove and modify /etc/modprobe.d/usb-load-ehci-first.conf to ohci load first
- tried to add "irqpoll" as kernel option
- echo Y > /sys/module/usbcore/parameters/old_scheme_first
No luck.
EDIT2:
Alright people. The device is gone for good. Other computers cannot see it as well, neither Windows 7 on media center or Ubuntu on laptop. Dunno if Arch fried it somehow ^_^

[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.

[SOLVED] USB sound card problems and audio setup

I want to clarify and correctly set up my ThinkPad T61 sound system finally.
I'm running Arch64 + KDE.
There are two sound cards - the internal HDA Intel and external USB CM118.
aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Set [C-Media USB Headphone Set], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: Intel [HDA Intel], device 0: AD198x Analog [AD198x Analog]
Subdevices: 0/1
Subdevice #0: subdevice #0
card 1: Intel [HDA Intel], device 1: AD198x Digital [AD198x Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
First of all, why are there both analog and digital subdevices?
I just need playback and/or recording support for these applications: opera, firefox, skype, clementine, mplayer, vmplayer. As high quality as possible.
Per-application sound control would be nice but if that adds too much clutter, I could live without it. No need for audio streaming or any other luxuries.
All the applications should use the USB card whenever it's plugged in. The internal SC should take over when CM118 is unplugged.
The problem is that most of the time it doesn't work. For example, if I plug out the USB card and then run some application like Clementine or Firefox there would be no sound ("connection refused" in Clementine).
Here is my asound.conf:
defaults.pcm.card 0
defaults.pcm.device 0
defaults.ctl.card 0
Also kMix/amix should switch the master channel from HDA Intel Master to C-Media Master automatically. The only way to do this is to write some kind of script, right?
AFAIK the following audio components are installed: ALSA, OSS (for some unknown reason), Phonon, Gstreamer.
I guess I can uninstall OSS without worries as no one seems to need it (checked with "whoneeds").
What about that Phonon? Would it override the asoud.conf if I set default device there? Why there are so many different devices in the Phonon configuration list:
C-Media USB Headphone Set, USB Audio (Default Audio Device)
C-Media USB Headphone Set (USB Audio)
C-Media USB Headphone Set, USB Audio (IECblablabla)
hw:1,0
hw:1,1
default
Intel Analog
Intel Digital
blablalba
And that C-Media triplet for every USB port the CM118 has been plugged in.
Too much confusion! All that mess for just two different cards.
So what is the proper way of setting primary and secondary sound cards in this situation?
Thank you!

I am sorry for my very late response and the lack of structure in my post.
I did some investigation and found a rather acceptable workaround for one of my problems described below.
Here is the basic functionality I need:
1. Automatic (on the fly) switching to the external sound card when it's plugged in and automatic fallback to the integrated SC when usb is unplugged.
2. Automatic (on the fly) switching of the kMix's master channel according to the changes mentioned above.
As for the first problem, I found this udev rule:
KERNEL=="pcmC[D0-9cp]*", ACTION=="add", PROGRAM="/bin/sh -c 'K=%k; K=$${K#pcmC}; K=$${K%%D*}; echo defaults.ctl.card $$K > /etc/asound.conf; echo defaults.pcm.card $$K >>/etc/asound.conf"
KERNEL=="pcmC[D0-9cp]*", ACTION=="remove", PROGRAM="/bin/sh -c 'echo defaults.ctl.card 0 > /etc/asound.conf; echo defaults.pcm.card 0 >>/etc/asound.conf'"
This solution has some disadvantages but it is acceptible. If you know of any better solution, please tell me.
For the second problem, I found this script which uses qdbus org.kde.kmix /Mixers org.kde.KMix.MixSet.setCurrentMaster method to set the master channel. However, I think that constant monitoring for the usb SC being plugged is not very effective. So I thought appending the following code to the second line of the previous udev rule would do the work:
, RUN+="/usr/bin/qdbus org.kde.kmix /Mixers org.kde.KMix.MixSet.setCurrentMaster "ALSA::C-Media_USB_Headphone_Set:1" "Speaker:0""
But that results in some weird behaviour: master channel stays the same but there would be three new tabs in the kMix window now: USB Set", USB Set# and USB Set$.
Here's what log messages tell us:

You see, the probe thing is running multiple times!
And here is an excerpt from udev debugger:
starting '/usr/bin/qdbus org.kde.kmix /Mixers org.kde.KMix.MixSet.setCurrentMaster '
'/usr/bin/qdbus org.kde.kmix /Mixers org.kde.KMix.MixSet.setCurrentMaster '(err) 'Could not connect to D-Bus server: org.freedesktop.DBus.Error.NotSupported: Unable to autolaunch a dbus-daemon without a $DISPLAY for X11'
'/usr/bin/qdbus org.kde.kmix /Mixers org.kde.KMix.MixSet.setCurrentMaster ' [2769] exit with return code 1
'/usr/bin/qdbus org.kde.kmix /Mixers org.kde.KMix.MixSet.setCurrentMaster '(err) 'Could not connect to D-Bus server: org.freedesktop.DBus.Error.NotSupported: Unable to autolaunch a dbus-daemon without a $DISPLAY for X11'
Some kind of X11 problem... And also happening twice! Why?
Running the setCurrentMaster method in terminal works very nicely, so the problem must be the way udev runs it.
One last thing - sometimes the usb SC automatically reconnects (disconnects and connects). I read somewhere that most probably the usb device makes the trouble, but maybe there are other possiblities?

[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/
$ cat /proc/asound/cards

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:

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

[SOLVED] Alsamixer always on 0 vol. when plugging in USB sound card

Hi.
I have another newbie question!
This time my problem is about sound.
Every time I plug in my USB sound card, alsamixer forgets its previous volume and sets it to 0.
I tried "alsactl -f /var/lib/alsa/asound.state store" as said in the wiki for storing the settings, even tried to delete the file before doing so.
I even tried simply "alsactl store" or something like that.
No matter how many times I set it to 100, alsa just forgets it. In pavucontrol I see the volume meter showing that the sound is okay (I guess I mean the sound stream?), but I have to start alsamixer every time I want to use my USB sound card. And because it's a notebook, I usually plug/unplug it like 5 times a day, so keeping it plugged in is not an option.
Just because of curiosity I tried it on a Fedora 15 live and it was working like a charm so I know there is a solution, I just can't find it.
What should I do?
Thanks in advance!

Sorry, but I failed.
First, I tried "ls -ltr /dev/$(find /dev -type f)", output:
[martin@faye ~]$ ls -ltr /dev/$(find /dev -type f)
ls: cannot access /dev//dev/shm/pulse-shm-1778335859: No such file or directory

The first line seems to be wrong, so the command modified to this: "ls -ltr $(find /dev -type f)", output changed to this:
[martin@faye ~]$ ls -ltr $(find /dev -type f)

To be honest, I don't even know what I should see here... :S
Typing "udevadm control --log-priority=debug" haven't told me anything, so I don't know if it was okay or not.
Afterwards I started Fedora live, went to the udev rules, the only suspicious file was "90-alsa-tools-firmware.rules", but it was about loading some firmware for some specific sound cards.
After reading that, I tried this rule:
SUBSYSTEM=="usb", RUN+="/root/alsa-usb.sh"
- It was a failure.
After searching in the above mentioned link and the Arch udev Wiki I tried this:
KERNEL=="sd*", SUBSYSTEM=="usb", RUN+="/root/alsa-usb.sh"
- Failure as well. Kernel "sd*" because I don't know what else.
Then I google'd some more and the closest I could find was the following:
KERNEL=="audio1", SUBSYSTEM=="sound", RUN+="/root/alsa-usb.sh"
- Failure.
At this point I don't know what to do. (Strange, eh?)
I guess my udev rule is incorrect in 2 points: kernel and subsystem. How could I check those? I tried lspci, because I've heard about it somewhere, but I don't think it is useful for me.

USB Sound Problem

I'm having a problem with my Bose USB sound system that has just recently developed. The system is plugged directly into the back of my Mac Pro desktop so it's not going through any hubs or secondary systems. When I first start my computer the sound works just fine. But after about 10 to 15 minutes of use the sound stops completely - as if the sounds have been turned off. If I boot into Windows 7 using Boot Camp, the sound system there works just fine with no problems at all, so I do not believe this issue is hardware related but is something associated with OS X.
This all started recently after installing Tinker Tool and then realizing that their latest version is not compatible with Snow Leopard. I followed their directions and told Tinker Tool to restore the previous settings and then I removed it from my system. Now, I'm having this USB sound problem. I think it's highly probable to be the cause of my problem.
Is there anyway to reinstall the USB drivers in OS X without reinstalling the entire OS? Or, is there something else I can try to restore the USB function to Snow Leopard? Many thanks for any tips or suggestions.

They are plug and play.
I did try unplugging all of the USB devices and then powered off the computer and unplugged it for about 5 minutes as I heard that that sometimes solves USB problems. However, upon reconnecting the problem returned. All other USB devices seem to be working normally - it's only the Bose sound system. I tried plugging it into a different USB port in the back of the computer but the problem continued after about 10 minutes. Therefore, I am convinced this is not hardware related.
At this point I am thinking I need to reinstall OS X Snow Leopard to undo whatever Tinker Tool damaged. Is it possible to just replace the USB drivers in OS X without reinstalling everything?

Audio and video skip after installing USB Sound Blaster Audigy 2

Hi community,?Since installing my USB Sound Blaster Audigy 2 NX, audio and video skip when being played with either windows media player, winamp, iTunes, neroshow, winDVD 7, creatives own media players etc. in fact anything I can try, won't work. Games are fine, in fact the sound is brilliant. I'd be really grateful for any feedback on this, not being able to listen to music is driving me crazy. Thanks.

Hello thebro90,I had the same problem.After tryed everything, uninstall, reinstall audio drivers, etc, I finally manage to solved it by updating the CPU drivers... I have a AMD Atlhon X2 4800+Never had the problem again.Best regards.

Satellite A500D-10E - USB sound is cracking/jittery during playback

Hi!
I'm having some problems with my USB Audio on my Toshiba A500D-10E.
The sound is cracking/jittery during all sound playback. Even system sounds when the computer is otherwise idle.
I have tried two different USB sound devices (Creative Arena USB Headset and Sandberg USB Sound Box 7.1), both with the same crackling sound, both working just fine on two other laptops.
It's not feedback noise, It is only when sound is playing I get the crackling sound.
When no sound is playing, the speakers are quiet.
The Conclusion is that there is some fault with running audio trough my USB ports.
Mouse, harddrive etc works just fine over the USB ports.
Running sound trough my onboard soundcard works just fine, except it does not have analog 5.1 output available, thus I need an external sound device to get analog 5.1 sound output. I am now using the Sandberg USB Soundbox 7.1 to achieve this.
I have tried the following:
Installing the newest drivers for the USB box
Tried using the windows-provided generic drivers.
Reinstalled Windows (twice)
Tried all the different usb ports
Tried without any other usb devices plugged in
Adjusted the output bitrate
Disabling the onboard soundcard
Disabled all other sound devices, including recording devices
I have the newest BIOS update (1.20)
I have a Toshiba A500D-10E laptop
2.3GHz Dual core prossessor
4GB ram
Radeon HD 4600 series VGA card
Windows 7 Home Premium 32bit
All USB ports are USB 2.0 compatible.
Could you please help me solve this problem? I've done some research and think there might have
something to do with IRQ sharing, allthough I can not find any good explainations as to how I would go about to fix it.

>Like I said, I have tried two different USB sound devices (Creative Arena USB headset and Sandberg Soundbox), both work just fine on other laptops I've tested them on, neither works on mine. So I don't think it's the external sound devices.
Did you test this with different installed Windows systems?
How about power saving for USB ports?
Try to disable this.
Try to connect also the external USB sound card to an external USB hub with an own power supply
Would be interesting if the same happens too.

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.

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.

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.

Please Read this ! USB Sound Blaster 24-Bit External : The Story of the endless problem

In order to keep the good behavior here (I`m really pissed off !) I just?want to tell you something (this is ESPECIALLY for all the guys from the stuff)?Before 2 days I`ve decided to buy a new sound system for my room. I bought myself Creative Inspire t600 5. surround system. Cool. I was very happy. I?needed only to buy a sound card?working with 5. because I have a notebook DELL INSPIRON 50 who has only 2 canals. So in order to be everything beautiful I gave $70 for Usb sound blaster 24-Bit external. And from that time the problems began. In short :? I was using Vista but I found out that it wont work with this soundcard. The first problem : Didn`t identify the device. I tried with several drivers... Nope. No sound card with Vista.(This problem seems to appearance with many owners like me)?I pluged the usb soundcard in my old pc running XP and it worked . PERFECTLY. So I removed Vista from my notebook and intalled XP. This took me whole day to rebuild all my software. Finally it left to set up the sound drivers. The cherry of the icecream. Aaaaand ..... **bleep**. When I play?any track it CRACKLES. Again problem appearanced with many here. I tried to find out here what is the problem but unfortunately as u can see my english is quite bad?so I cant understand?what I need.I really like Creative but if they cant manage this problem I will?no longer buy their stuffs??JUST PLEASE SOMEBODY ANSWER ME IS THERE ANY SOLUTION FOR THIS OR NOT. I JUST WANT STRAIGHT ANSWERPS : Please do not delete my post. I know there are plenty like this. I dont want this crackles

well ?

External USB sound device with SPDIF In?

Hi all,
I would like to know if Creative has any external USB sound cards with a SPDIF interface that works with Windows 7. I have an Extigy, and as I know it, it will not work with anything newer than XP.
I need a USB card with SPDIF input to bridge my Astro b.yond 5. SPDIF audio to my 5. speaker kit. For various reasons I cannot change the existing sound card in the computer.
Please help.

I don't know that sound card or application software, but the usual reason for this is that somehow you have reverted to the Microsoft wdm drivers rather than the asio ones you need for multi channel use.
This sometimes happens with some usb interfaces if you have connected the interface originally before installing any drivers. Removing any drivers associated with usb audio and then re-installing them might be worth a try.

MULTIPLE USB SOUND BLASTER in ONE SYS

Message Edited by abifar on 0-02-2005 04:46 PM

I?m having the EXACT SAME problem. I thought it was something isolated, but apparently it isn't.
Sound just "pops" and "shutdowns" at an irregular interval of time, which is extremely annoying. I've noticed that it depends highly on the usage I'm giving the PC at the moment. When it's jsut sitting there plkaying music, it rarely happens. But if I'm browsing the web, with sites heavy on images or working on several tabs at the same time, it turns into a 0 second thing, making music almost unbareable... installing ANYTHING at the same time kills anything, 2-3 second pops and fades.
Before you even suggest it, I have a rather high end PC, phenom II 4 cored PC with 4GBs of RAM and a Caviar Black Hard dri've, so it's NOT that the PC can't handle the load. Its jsut browsing with music in the background... with half decent drivers, a 5 year old Celeron PC should be able to handle that...
I've read those troubleshooting guides over and over, and it's amazing how they suggest to shutdown/disable numerous things tha twill kill performmance in other areas, so we can have a functional audio solution. The only suggestion that makes a lot of sense is IRQ sharing with components, such as video cards/SATA dri'ves. I haven't checked/tried that, because unfortunately I'm not quite sure how/where to change the IRQ values... any help there?

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:

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"
