Re: [Alsa-user] Alsa simultaneous use of usb-sound card - BW problem
PS: IIRC this year it was discussed at Linux audio user mailing list [1], if it's possible to sync two USB sound devices. My professional PCIe card provides a professional sync option, however, IIRC my prosumer PCI Envy24 cards don't provide a sync option, but AFAIR it's possible to use S/PDIF to sync those cards.

Re: [Alsa-user] Alsa simultaneous use of usb-sound card - BW problem
No sync is needed, i only want to use 2 usb sound cards at the same time (different streams, eg: 2 terminal open and i want to make arecord -D plughw:1,0 | aplay -D plughw:1,0 for first usb card and arecord -D plughw:2,0 | aplay -D plughw:2,0 for second usb sound card. I dont need to create virtual devices, i only want to use these 2 cards at the same time, When i use these cards with different usb buses, it is ok but i need to use them in same bus. The same bus situation results in a problem about bandwidth,i am surprised at seeing the bandwidth error. -- Infragistics Professional Build stunning WinForms apps today!

[Alsa-user] Asus xonar DGX card issues
Hi Guys, I'm running an Arch linux system and I'm having some issues with my Asus xonar DGX sound card. Now what is confusing to me is that supposedly according to the ALSA website. The front panel audio for this card (including mic) shouldn't work but the back panel should. However I am experiencing the exact opposite, where my front panel works but not the rear. I currently have a 2.0 system but all the options I get for analog out include 4.0,4.1,5.0,5.1. http://www.alsa-project.org/main/index.php/Matrix:Vendor-Asus is where it says the front panel doesn't work. I tried troubleshooting with a member on the Arch forums which refered me here. The link to that is https://bbs.archlinux.org/viewtopic.php?pid=1442762#p1442762 I would love to know what you guys think! Thanks in advanced.

Does 2.0 full speed-compatible mean USB-2 class compliant or is a special driver needed? USB 2.0 is not the same as as USB Audio 2. (USB 2.0 adds the high-speed mode, i.e., 480 Mbit/s. USB Audio 2 is a specification that allows conformant drivers and USB 2 devices to work together.) Nowadays, Linux does support USB Audio 2. (As do OS X, and FreeBSD; the only holdout is Windows.) perhaps the bandwidth really is to small. Indeed, that is why the error message says bandwidth. Please note that USB 2.0 *adds* high speed mode, so it is still possible to have devices running at full speed (12 Mbit/s). Bandwidth is measured in time, not bits, so a bit from a full-speed device takes as much bandwidth as 40 bits from a high-speed device. A single stereo full-duplex device can easily max out a full-speed bus. If you want to use two of them, connect them to *different* buses. (Check the output of lsusb -t to see which bus they are connected to.) Regards, Clemens -- Infragistics Professional Build stunning WinForms apps today!

I don't know why this is, but I spent a long time trying to figure out what was wrong with my configuration, the kernel, the Alsa driver, etc etc when I finally in desperation plugged the card into one of the other USB ports and POOF all worked fine. So, if you have a different set of USB ports or a different machine to try, you might want to give that a go first. My machine is a Thinkpad X200 with dock. I tested USB ports on both sides of the Thinkpad and the dock ports. Also I tested without any other USB devices present but none of that helped. I just thought of this.. maybe I should test on my monitor's USB hub. I lack the necessary USB A-B cable at the moment. I tested using Foobar on Win7 in my university's library on a Dell machine and the DAC worked properly. I don't have other Linux machines at the moment to test with. Beyond that, I have a completely vanilla configuration (no messing with Alsa configuration files). I continue to let Pulse Audio live on my system, and the default sound card is the Intel stuff delivered with the machine. So all alerts and system audio go through that subsystem, and only Guayadeque uses the Dragonfly. I don't have pulse installed. I did have pulse installed before I got the DAC but I uninstalled it during testing of this issue. I have jack installed but it isn't running. I installed jack during testing of this issue and I learned something about it: jack uses padded s32le for 24 bit devices. If the device doesn't support s32le it falls back to s16le. 'true' 24 bit in jack is currently unavailable: http://linux-audio.com/jack/ jack wouldn't work with the DAC in any configuration except for 96000 kHz 16 bit, which is interesting. I didn't include my jack results earlier because it is seems irrelevant. Also, generally I plug in the Dragonfly after the machine is booted, so all other audio configuration is probably pretty stable and configured by the time that happens. I have tried both methods with the newer kernels but neither works. The working 3.12 kernel is with device plugged in from boot. Let me know if you want me to collect any more data for you from my end. My lsusb -v for DragonFly in Debian kernel 3.12-1 is identical to Ubuntu kernel 3.13.0-32.
