Patch for version 3.13.0
Marantz devices have a few other quirks to support DSD format. Does yours also support it? Yes, it also supports DSD. And can you test DSD functionality? If yes, you can take a look at the latest code and enables the all places for your Denon device. I only have a few DSD files (both 5.6MHz and 2.8MHz), and those already seem to work OK with kernel version 3.13.0. This version only has one place with code for Denon / Marantz devices. I saw the latest kernel on git has two more places. Would it make sense to try to backport those parts of the code to 3.13.0? I'm asking because I'm not sure yet whether I will be comfortable playing around with the latest kernel on my (only) desktop system. Simply try the latest kernel as is. The backport has always a risk of mistakes. Usually you can install multiple kernels on a machine, and keep the good running one. Created attachment 167361 [details]

Patch for version 3.19.0+, compliant style
I hope this is compliant --- first time I am submitting a patch.
Thanks. I submitted to ML and will merge to upstream later. It'll be included in the stable kernel then. Cool. Thanks a lot! |
Denon DA-300USB DAC is recognized by "aplay -L", but playback fails with error message: "clock source 41 is not valid, cannot use" Lsusb reports the device as: Bus 002 Device 014: ID 154e:1003 D&M Holdings, Inc. (Denon/Marantz) Possible fix: treat this device the same as other Denon/Marantz devices, like in the patch below. Works in my case. ============================================================================= --- linux-3.13.0/sound/usb/quirks.c.orig 2015-02-13 17:45:21.406145714 +0100 +++ linux-3.13.0/sound/usb/quirks.c 2015-02-13 17:27:24.116413460 +0100 @@ -1135,6 +1135,7 @@ void snd_usb_ctl_msg_quirk(struct usb_de (requesttype & USB_TYPE_MASK) == USB_TYPE_CLASS) { switch (le16_to_cpu(dev->descriptor.idProduct)) { + case 0x1003: /* Denon DA-300USB */ case 0x3005: /* Marantz HD-DAC1 */ case 0x3006: /* Marantz SA-14S1 */ mdelay(20);
