Audio problems with an USB interface

Hi everyone, this is my first post and glad to finally do it.
I am so pleased with arch linux, it's just simply amazing. I have learnt a lot following the wikis, it's pretty simple and effective.
I managed to install and configure ssh server, samba server (surprisingly easy), usb samsung laser printer, nvidia drivers, KDE desktop (so fast in arch), fonts, cpu scaling and I'm so happy with the results and perfomance.
The only problem I ran into is about audio, I think the wiki on audio is pretty incomplete (don't get me wrong I enjoy your work).
The problem is with an USB interface line 6 toneport gx (http://line6.com/toneportgx/), I know the device is meant to be an usb guitar interface but since I don't longer play guitar I use it as soundcard. As complementary information it works with no problem on Ubuntu 10.04 (which is the distro I came from).
The interface works and it's unmuted since I dmix does not work when I try to play sounds from different sources I had to install pulseaudio. Pulseaudio works partially, the sound was improved and finally I am able to play different sources. The big problem is when high cpu load ocurrs the the audio dies and does not come back even when the cpu loads decrease.
Any help is appreciated.
Thanks.

You may want to debug pulseaudio (check their wiki to see how, involves running pulseaudio in verbose mode) to see what happens.

Audio problems with a USB turntable using Linein, right channel not playin

I have an Audio Technica usb turntable and I am using Linein software to get the audio in. I am now missing the right channel. I use the USB connection and I have tried different cables so that is not the problem. I also tried using the RCA cables, plugged into the micro phone/line-in port via an an RCA to single stereo adapter up which did not solve the problem either. In fact when I switched the red white, left right cables the sound still only came out from the left channel and subwoofer. Both channels work fine with Itunes so it is not the speaker system. I am thinking that it is a setting problem with the software either the Linein or Mac OS. Does anyone use Linein and what settings should I be looking at, Midi settings, Sound preferences? Thanks.

USB audio problems with 2013 iMac

I'm having a strange audio problem with USB microphones and headsets. The issue with my Logitech H650e is shown in this screencast I recorded. In the first part of the screencast, I am not speaking into the mic—yet you can see the levels fluctuating as if there is static playing (not in a natural pattern that you'd see when someone is speaking). In the next part of the video I demonstrate that selecting the built-in iMac mic for input, and then re-selecting the Logitech headset temporarily solves the problem. You can see the input start to fluctuate normally as it should when I am speaking. But at 0:31 in the screencast, you can see the input levels freeze and stop registering anything. I continued to speak until the end of the screencast, but no input was detected. For this screencast, I was on a Go To Webinar call, but the problem occurs regardless of whether I'm using Skype, Go To Webinar, GarageBand or any other software.
The problem with my Blue Yeti USB microphone is also different. In that case, the input does not freeze as it does with the Logitech headset. The levels appear as you would expect, and it seems to work. However, the person on the other end can hear static in the background, even though I don't hear it in my own headphones. I learned this because I just tried to do a Skype interview with the Blue Yeti, and the interviewer told me they could hear static. We closed Skype and called each other back twice, but the problem persisted. Then, suspecting the problem was related to what I described above with the Logitech, I unplugged the Yeti and then plugged it into my Macbook Air 2013 (also running Mavericks). Lo and behold the static completely disappeared.
My Griffin iMic and Audio Technica lavalier mic (attached to the iMic) behaves similarly to the Yeti, except in this case I can hear the static when I speak with my monitoring headphones. The input works but I get a lot of cracking and static in the background. This was confirmed by calling the Skype Test Call number and recording a message, which is then played back.
Here are the facts:
All 3 of my USB audio microphones/headsets do not work with my 2013 iMac running Mavericks
All 3 of these microphones/headsets worked fine with my 2008 Mac Pro running Mountain Lion
All 3 of these microphones/headsets work fine with my 2013 Macbook Air running Mavericks
In this other thread, several people are reporting similar issues with the iMac 2013 and Mavericks. At least two people did not have the issue when the iMac 2013 was running Mountain Lion. This of course suggests the issue is the combination of the iMac 2013 and Mavericks.

Firewire audio problems with OS X 10.5.6

Hello,
I’m experiencing audio problems with Firewire 400 on my Macbook running Mac OSX 10.5.6.
I’ve got a 2.4Ghz IntelCore 2 Duo with 4 GB RAM and 59 GB available on the internal HD.
It’s hooked up to a brand new Mackie D.4 mixer with 2 Firewire outputs. The problems occur on both Firewire outputs.
I’ve installed automatically from the software update (which I will never do again) to 10.5.6. I never tried the D.4 with 10.5.5 so I can’t tell if the problems occur there also.
The main problem is that after a couple of minutes of recording the sound starts to break up and get really distorted. After a while the sound comes back again.
The second problem is that Soundtrack Pro or Audacity don’t get any audio input from the D.4, although audio input is clearly visible in System Preferences – Sound.
The only sound program that works with all 14 Firewire channels is Ableton, but also in Ableton the distortion occurs.
An example of the distortion can be checked here:
http://media.kaalslag.com/firewire-distortion-problem-mackieD4+Macbook.mp3
I’ve roamed several forums and sites to solve the problem and I tried these solutions:
I updated again to 10.5.6. with the full combo download from the Apple site. Restarted. Problem still there.
I shut Airport off, because lots of sites mentioned problems with Airport conflicting with audio/firewire. Didn’t work.
I did the work around with shutting the Macbook off, disconnecting the D.4, restarting the Macbook, opening Audio/Midi Setup, connecting the D.4 again, toggling the format frequencies a couple of times. Again, no use.
Right now I’m using my “old” Macbook again to record from vinyl. This one is still running on OSX 10.4.11. No problems so far.
I’ve had the distortion problems occuring before with an USB interface. Hoped that the Mackie Firewire would solve the problem, but it seems now that there’s a serious audio Firewire problem which is still not solved in OSX 10.5.
Any help, tips and/or a work around would be much appreciated. Thanks!

You could try using another computer in Target Disk mode (as an "external HD"), or you can connect the firewire cable and disconnect all other network cables (turning off airport). Then on each computer go to the "Network" system preferences and select "Built-in Firewire" from the list of ports and choose "Manually" from the drop-down menu next to "Configure". Enter the following IP addresses and subnet masks, apply the changes.
_Computer 1_
IP Address: 192.168.1.1
Subnet Mask: 255.255.255.0
_Computer 2_
IP Address: 192.168.1.2
Subnet Mask: 255.255.255.0
After those ip addresses are entered and you've clicked "Apply", ensure that for both computers you have file sharing enabled (done in the "Sharing" system preferences), and then check the Finder sidebar to see if the computers can see each other (their names should appear under "Shared" in the sidebar--if not, try restarting).
If the computers dont appear (even after restarting), using the "Connect To" option that's available in the Finder's "Go" menu. In there, to connect to another computer enter it's IP address as follows:
afp://IP_ADDRESS
If you're on the computer with the ip address of 192.168.1.1, you would enter 192.168.1.2 as "IP_ADDRESS". The "afp" is the protocol (just like "http" for web), and stands for "Apple Filing Protocol"...Apple's file sharing protocol.

Problem with SB1240 USB sound card

I'm pulling hair here! I've just bought a SB240. Windows (XP Pro, SP3) detected it and I can select it fine for listening. But when I open Sound and Audio Device Properties and select Sound Recording/Volume, I see the Capture panel with the three inputs, but all the controls are greyed out and immovable. I also use the application "Total Recorder" by High Criteria, in which I can select the SB240 device but the only input line it sees is SPDIF Interface.
I'm stumped. Can anyone help?
John?

&Re: Problem with SB240 USB sound card
Thank you. I did a complete uninstall, including the device itself (from Device Manager) as well as all drivers and any SB related software. As recommended by Creative, I had previously installed the driver software from the supplied CD and that seems to have been the problem.
I let Windows re-detect the SB, but? got a "problem ... device may not work correctly.." during the detection, so I was not hopeful (this had not happened the first time I installed the device).
Nevertheless it now does work fully and is properly configured in "Total Recorder" too.
So I would suggest not using the supplied drivers and software - at least not in WinXP. But it's not very confidence inspiring.

Problems with the USB Ports

Hi there,
I writing this because I'm having some really big problems with my USB ports.
A few days ago I plugged in an USB-Hub that was quite cheap. Suddenly a window popped up saying that a USB device was deactivated because it "needed" to much power. Since this happening, two of those windows keep popping up everytime I boot the MacBook. I called Apple and got some help: I had to delete some .plist files and clear some caches. The man who helped was able to find the error and deactivate the notification, he also told me to make a PRAM- and a SMC-reset. The man said that it's just a software problem and that I have to reinstall the system if we don't find a solution. So, one day later I reinstalled the system (Lion) and not only didn't it help, the two notification windows were popping up again...everytime I booted the Mac. So I decided to formate the whole hard drive and install Snow Leopard -> still the problem with the USB ports. After that I installed Lion -> still the problem with the USB ports. I even tried to extract the .kext files that are important for the USB functionality from an earlier Combo Update, but it didn't help either. The point is, that the Mac doesn't recognize my external hard drive or any of my iDevices. Sometimes it recognizes USB sticks, but only after 20 seconds. The data transfer on both USB ports is also very slow. If I'm lucky and Mac recognizes one of my USB sticks, it takes like an hour for 1GB to be transfered on the USB stick or from the USB sticks to the Mac.
I really don't know what to do and need help, especially because my backup data is on my external hard drive which I can't access because of this problem.
I really hope that someone can help me, I'm very thankful for every answer that could help me!
PS: Sorry for my bad English, I hope that everyone understands what I mean, please tell me if you don't get what I'm trying to explain in the text above.
Sincerely,
iLoud
[UPDATE] I downloaded "USB Prober" and copied the Output file, maybe it helps:

Audio problems with Droid/X

When sending voice messages using Cloudtalk, the recipient hears only garbage. I contacted Cloudtalk technical support, and it appears that the 3gp file sent by the phone is not recognized. This problem is known by them, and happens only on Droid/X.
Anyone else is experiencing audio problems with the droid/x?

That doesn't sound like an audio issue with the X, it sounds like a compatibility issue between the X and the service.

Audio problems with CHS 435

Hello all, I'm having audio problems with my FiOS set top box. When I start to change channels I lose audio and can't get it back unless I turn the TV off/on or I change the HDMI source on my TV . Seems after changing a couple of channels the problem happens. I've tried the in home agent auto correct, and different HDMI cables. I have a Westinghouse TV and I'll try a firmware update for the TV and see if that fixes it. Any fix for this and the possibility that it might be the set top box ? I just got FiOS and all is going well besides this issue. Seems that the other STB that are model # 335 aren't having this problem.

Some TVs have had issues with the HDMI handshake and the Audio. You may be required to use the separate bulkier HD Component cables with separate audio cables. Or try it as a solution on that TV.
I have CHS 435 DVR on a Samsung, and 2 CHS 335s on different model Vizio TVs, all with HDMI, and no issues. Others have reported different issues. I did a search here with the following results. Perhaps this information will help.

Audio Problems with some HD channels (HBO mostly)

I'm experiencing sporadic audio problems with a handful of HD channels. Most noticably on HBO.
When the audio is output through the television itself, it sounds OK... however if the audio is output through my home theater receiver and speakers, I can hear a lot of static and "crackling" on certain movies and shows.
The issue isn't the home theater setup, as I have several other components that use it (AppleTV, Bluray, Xbox, etc.) and the audio sounds perfect from them.
The only device that displays that poor audio is the FiOS Set Top Box and even then it's only on a few channels.
I thought maybe that the optical audio cable between the set top box and the receiver may have been bad, so I replaced that. Same problem even with the new cable.
The problem is either with the Set Top Box itself or the audio levels on the stream from the channel provider.
Has anyone experienced anything similar to this, and if so... did you resolve it somehow?
Any help you could provide would be most appreciated.
Thanks!

Problems with wireless usb adapter on MSI K8NGM-V

Hi!
I have a 3Com (3crusb20075) wireless usb adapter, and a MSI K8NGM-V Mainboard. Very often the usb disconnects from the network and i have to reinsert it to work again. A friend of mine have the exact same adapter and that one fails too. He uses mine without problems. I therefore belive that this is a problem with the usb ports on my mainboard. Have anyone heard of anything like this? I wanted to try to update my bios but i don't have a floppy so msi live update wouldnt let me, and i could find the bios files on the msi webpage so i cant burn them on a bootable cd. Help please
(I trying turning of power save mode on the usb adapter, without any luck. Tested it in linux. Same result)

The ability to access the network, but not the Internet, typically indicates that the computer is not able to either find or negotiate with the DNS servers. The proper DNS servers would be provided by your ISP using DHCP. In turn, the AirPort would use DHCP to provide these to both the wired & wireless computers connected to it.

For each PC that is unable to access the Internet, temporarily include the following OpenDNS servers:
o Primary: 208.67.222.222
o Secondary: 208.67.220.220
You would enter these in the network TCP/IP settings for the respective PC's wireless network adapters. You may need to restart the computer in order for these DNS settings to "stick." After restarting, can you access the Internet with either or both of them?

Problem with detecting USB devices.. something abt ehci-hcd??

Hi All,
I have a DELL E6410 laptop. I have a problem with connecting USB devices.
Whenever a power event (such as connecting/disconnecting of AC adaptor) happens, my laptop stops detecting any USB devices and any changes that happen on the USB ports. That is, say an external mouse is connected to the laptop, the mouse stops functioning, and if I connect a mouse/USB_stick or any such thing to the computer, the device is not detected.
dmesg output show that any connecting/disconnecting events are not detected by the computer. lsusb output too shows the same thing.
To solve the problem, I need to rmmod the module ehci-hcd and modprobe it back. That is, I have to run the commands rmmod ehci-hcd followed by modprobe ehci-hcd. Then, this problem goes away until the next power event happens.
This event does not happen all the time, but it happens very regularly.
Here are the kernel and laptop specs..
uname -a
Linux myhost 3.0-ARCH #1 SMP PREEMPT Tue Aug 30 08:53:25 CEST 2011 x86_64 Intel(R) Core(TM) i5 CPU M 520 @ 2.40GHz GenuineIntel GNU/Linux
Kindly help me on this issue.
Thanks

This is the output of kernel.log when I unplug my AC adaptor with the external USB mouse connected.

After this the the mouse goes dead (the light on the mouse also goes off).
If I disconnect the mouse at this stage, there is no change in kernel.log. If I the mouse back too, there is no change in kernel.log.
Now, when I turn the AC adaptor on, this is the output on kernel.log

At this point, the mouse comes back to life (its light begins to glow) and I can move the mouse pointer on the screen.
The output of the grep command that rwd gave is too big (16000 lines) to be pasted here..
Thanks,

Cant hear song playback while recording with external USB Interface Mic in Garageband

Hi there
There must be something wrong with my settings in Gargaeband/Mac Sound Settings.
I have Garageband 9 (V5.1) running a song I have already recorded using a USB keyboard.
I want to record using my external mic and my USB Audio Interface, so
I select New Track> Real Instrument
I plug in my Yamaha Audiogram 3 USB AUdio Interface and I get a pop up stating
"Garageband is scanning your system for audio devices, and has detected a device named "USB Audio Codec"
If you want to use this device do not disconnect it during the scanning process.
Do you want to use this devise No/Yes."
I select Yes and INPUT SOURCE changes from
Mono 1 (Built-in Microphone)
to
Mono 1 (USB Audio CODEC)
I can see the signal lights lighting up on the audiogram 3 when I talk into the mic, so theres no problem there.
Also when I hit record I can record audio using the mic, and can see the levels (and the audio wave I am creating being drawn on the screen) but I cannot hear the track itself when I am recording using the mic. Nor can I hear the track or the new mic recorded audio AFTER I have hit stop.
The only way to hear the song again with the newly recorded mic track is to unplug the Audiogram 3 (Then I get another Pop-up stating
"The audio device "USB Audio CODEC" has been disconnected!
Do you want to switch to Built-in Audio or quit Garageband?"
I select USE BUILT-IN AUDIO)
Then the input source changes back to
Mono 1 (Built-in Microphone)
And I can hear the track again.
So my problem as you can see if that I cant hear the track while recording using the microphone with the Audiogram 3.
But I can record video with audio using the audiogram 3 USB Audio Inteface and mic using photobooth when I select change Sound>Input to USB Audio Codec in system preferences
It therefore assume it must be a problem with the internal audio settings of the mac/garageband.
Can anyone advise?
thanks!

In order to hear yourself while you are recording, you need to set Monitor to "ON" under the Track Info panel.
Also, what are your sound output settings? It sounds like you haven't selected the right output source.
If your speakers or headphones are plugged into your audio interface, then you need to go into Preferences -> Audio/MIDI and select your audio interface under Output as well as Input. If your speakers or headphones are built-in or plugged directly into your computer, then you need to select Built-In under Output.
I have a sneaky feeling that you are in the latter scenario, and that when you plug in your audio interface Garageband is automatically switching both Input and Output over to your interface, which means no sound output as long as the interface is plugged in.

Problems with H2 digital interface

I have a SoomH2, and a macbook, os 10.5.8. When I plug into the USB, to use as a mike for garage band, the sound going into the computer is all distorted and shows a solid thick wad of sound on the garage band recording level, despite turning down the gain on the H2 and/or the macbook. There is a backround of static, even if there is no sound going in. I have had the same problem with the power off, running off of the USB, with batteries and turned on, and with the external power. An old posting said to put a USB powered hub in between, but if I am already plugged in, with the H2 on, that should not be necessary.
When new, the H2 worked, but developed this problem intermittently, and now does it all the time. Put a new software version into the H2, no difference.
Used by itself, the H2 is fine, and you can download into garage band. The macbook internal mike does not have any problems, and goes into garage band just fine, but is not a high quality mike for music. Has anyone else had a problem like this, and how did you resolve it. Thanks for any help.

Hi Klaus
In your wsdl file the soap address tag (given below)
<soap:address location="http://xxxxxxxx:8000/XISOAPAdapter/MessageServlet?channel=:Foo_SOAP_Service:SOAP_Foo_out&version=3.0&Sender.Service=Foo_SOAP_Service&Interface=urn%3A%2F%2Fporeceive.xi.pse.siemens.com%5Efoo_out_sync" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"/>
is to be edited as
<soap:address location="http://xxxxxxxx:50000//XISOAPAdapter/MessageServlet?channel=:Foo_SOAP_Service:SOAP_Foo_out" />
because the soap address format should be like :
