Re: [SlimDevices: Touch] Announce: Enhanced Digital Output app - USB Dac and 192k Digital Ouput
Yes, I have tried both #12 and #11, applied from default kernel with all the settings reset prior the upgrade. Perhaps the issue is somewhere else, hence the patch does not even get the chance to do it's work? What has me confused is why the DAC does not show up in aplay -l or /proc/asound/cards. I know it uses the Tenor 8802 chip and that it is detected in newer live CD linux systems. shkorc's Profile: http://forums.slimdevices.com/member.php?userid=57025 View this thread: http://forums.slimdevices.com/showthread.php?t=94512 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
Re: [SlimDevices: Touch] Announce: Enhanced Digital Output app - USB Dac and 192k Digital Ouput
Hi again, I received this information from a friendly user at the alsa-user mailgroup: The problem is that there's a gap in the interface number allocation: Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber0 ^^^ [...] Interface Association: bLength 8 bDescriptorType11 bFirstInterface 2 bInterfaceCount 2 [...] Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber2 While this doesn't make any sense, it is actually fine, but the USB core code in older kernels doesn't like this and fails. I fixed this just recently here: https://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=b3a3dd Here's the whole output from the Linux machine: https://dl.dropbox.com/u/1184591/mageia/lsusb-v.txt Can the fix be applied to Touch's kernel? I can test, no problems with that :) shkorc's Profile: http://forums.slimdevices.com/member.php?userid=57025 View this thread: http://forums.slimdevices.com/showthread.php?t=94512 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

Re: [SlimDevices: Touch] Announce: Enhanced Digital Output app - USB Dac and 192k Digital Ouput
I have experimented with another Linux distro beside Ubutnu, i.e. Mageia. It is also running Alsa 1.0.25 but for some reason the DAC is not visible in /proc/asound/cards even though it is mentioned in dmesg. I'm guessing the issue is not because of Alsa version, but something else. I have run a script from alsa that gathers relevant information from: dmesg lspci lsmod aplay amixer alsactl /proc/asound/ /sys/class/sound/ ~/.asoundrc (etc.) Ubuntu output: http://www.alsa-project.org/db/?f=5a596af9293e754c598b010fa5749a5b19cc4275 Mageia output (Mandriva Fedora): http://www.alsa-project.org/db/?f=18113235752e29ecd31a20b8506b6e173cd4bc3c Does the difference between the two give any clues for you? I'm assuming if we find the difference and apply the necessary changes to Mageia and it starts working, then it might be possible to do the same with the Touch kernel? shkorc's Profile: http://forums.slimdevices.com/member.php?userid=57025 View this thread: http://forums.slimdevices.com/showthread.php?t=94512 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

Which version of Alsa is running on the Touch? Can it be upgraded or is this something Logitech must do first? shkorc's Profile: http://forums.slimdevices.com/member.php?userid=57025 View this thread: http://forums.slimdevices.com/showthread.php?t=94512 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

Re: [SlimDevices: Touch] Announce: Enhanced Digital Output app - USB Dac and 192k Digital Ouput
Reply from support: the DAC-9 should work on OS X for USB audio class 1 and 2. As for Linux we do not know if it will work. Someone may have developed drivers that work but we do not support it. Bummer. If I'd only get some confirmation as to which chip they use, perhaps it could be integrated in the kernel. shkorc's Profile: http://forums.slimdevices.com/member.php?userid=57025 View this thread: http://forums.slimdevices.com/showthread.php?t=94512 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
Re: [SlimDevices: Touch] Announce: Enhanced Digital Output app - USB Dac and 192k Digital Ouput
Opening the DAC-9 and examining the USB module, the USB transceiver chip says NuForce NFUSB192S 12W12, which does not help much in term of drivers. I received some unconfirmed information that it might use a Tenor 8802. I tried using Kernel #12 but the DAC was not detected during reboot. I will install Linux on a spare laptop I have and test if it works from the box. Do you have any suggestion as to which distro I should use? Is a live CD enough or do I need to make a full setup of the operating system? shkorc's Profile: http://forums.slimdevices.com/member.php?userid=57025 View this thread: http://forums.slimdevices.com/showthread.php?t=94512 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
Re: [SlimDevices: Touch] Announce: Enhanced Digital Output app - USB Dac and 192k Digital Ouput
I apologize for repeating my question, but would anybody know if it's possible to test a DAC with a desktop Linux and from some output assume it will work with EDO? I don't own a Touch, I'd like to make sure it works with my dac before a purchase.

Re: [SlimDevices: Touch] Announce: Enhanced Digital Output app - USB Dac and 192k Digital Ouput
I currently don't own a SBT (only a Duet) but would definitely make the upgrade if I'd only know if EDO will work with my dac (Nuforce DAC-9). Is there a way I can test the dac with a live Linux distro on my laptop and could see from there if it will work together? I really appreciate your reply guys, thanks. Might help someone else wondering the same thing.
