[alsa-devel] Alsa: USB Class 2 Audio soundcard device disappears suddenly
It doesn't show anything when that happens. Looking at dmesg (I'm attaching it), it shows this: [ 350.170478] usb 1-4: config 1 has an invalid interface number: 3 but max is 2 [ 350.170500] usb 1-4: config 1 has no interface number 2 [ 350.170843] usb 1-4: config 1 has an invalid interface number: 3 but max is 2 [ 350.170864] usb 1-4: config 1 has no interface number 2 [ 350.171344] usb 1-4: New USB device found, idVendor=21b4, idProduct=0230 [ 350.171366] usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 350.171385] usb 1-4: Product: Ayre USB Interface [ 350.171401] usb 1-4: Manufacturer: Ayre Acoustics [ 350.171418] usb 1-4: SerialNumber: (C) 2010 XMOS/Wavelength Audio Don't know if those 'invalid interface number' messages are relevant for the issue.

Hi,
I'm using an USB Class 2 Audio DAC (basically a soundcard) with my Linux box and MPD software.
It works great when playing files stored in a remote share, but when playing files from an USB pen, it stops playing in a few minutes.
Mpd.log shows this:
Code: Jul 30 13:03 : output: "USB" [alsa] failed to play: No such device Jul 30 13:03 : output: closed plugin=alsa name="USB" ALSA lib pcm_hw.c:1401:(_snd_pcm_hw_open) Invalid value for card Jul 30 13:03 : output: Failed to open "USB" [alsa]: Failed to open ALSA device "hw:0,0": No such file or directoryIt seems to be somewhat related to the USB bus not being able to cope with both PCM streaming to the soundcard and reading from the flash pen simultaneously, I guess.
So, anybody faced this issue previously and can provide some hints to solve this?
MPD is 0.17, kernel is 3.2.17, alsa-utils is 1.0.25.
Does the kernel log or 'dmesg' show anything weird what that happens? Daniel _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org http://mailman.alsa-project.org/mailman/listinfo/alsa-devel

Well, it shows: [ 349.789200] hub 1-0:1.0: port 4 disabled by hub (EMI?), re-enabling... I guess this about the time when the streaming stops? How does your USB wiring setup look like and what kind of system is that? Smells like a hardware issue, to be honest. You could do some stress-testing by transferring huge amounts of data from one USB storage media to another. Also try replacing the cables maybe. I'm Cc'ing the linux-usb list, maybe someone there has an idea. Daniel

You're right about the EMI message, it's happening when the streaming stops. I've tried different cables before, but that didn't solve the problem. The motherboard is an Alix 1D, and I'm using the onboard USB 2.0 ports. If this really is an EMI issue, guess I'll have to source some kind of miniPCI-USB 2.0 card and see if that solves the problem. ----- Original Message ----- From: Daniel Mack <zonque@gmail.com> To: Joao Bonina <bonina_2001@yahoo.com> Cc: "alsa-devel@alsa-project.org" <alsa-devel@alsa-project.org>; linux-usb <linux-usb@vger.kernel.org> Sent: Tuesday, 31 July 2012, 12:38 Subject: Re: [alsa-devel] Alsa: USB Class 2 Audio soundcard device disappears suddenly On 31.07.2012 12:12, Joao Bonina wrote:

Yes, try that. It could still be something else than an EMI issue, but something makes the hub reset its ports. Let us know what you find! Daniel

Another possibility is to put a USB hub before the sound device. That _might_ clean up the signal. Alan Stern

Thanks for that suggestion, Alan. I used a cheap hub that I had stashed away. At the begining that seemed to solve the problem. But after a while, some clicks and pops became audible. Disconnected it all for a while, and when I reconnected, the problem was back again with this message on mpd.log: Aug 01 05:57 : output: "USB" [alsa] failed to play: No such device Aug 01 05:57 : output: closed plugin=alsa name="USB" This time, there's no EMI message in dmesg. Still have to try copying files from one usb flash to another. João Bonina

Did the copying test and all went well there. Also did a usbmon session with the DAC disconnecting/reconnecting automatically. There was no EMI message in dmesg there, and I'm connecting the DAC through a USB hub. Analyzed the usbmon log with Virtual USB analyzer, but couldn't find reasons there for the disconnection. I'm not very experienced in this subject, so excuse me if I'm missing something obvious here. I have the usbmon log. If someone wants to take a look at it, please let me know and I'll send it.
