Linux Kernel Patch for Topping DAC users

[yue]

Linux kernel does not recognize Topping DACs' ability to play native DSD, as Thesycon's vendor id is not listed in the kernel.

I submitted a patch to solve that issue

https://git.kernel.org/pub/scm/linu.../?id=1ea0358ecb848058b35b6da13d7f4c08610a73a8


The code will probably ship with the next stable version kernel. But in the meantime, if you need to use Topping's DAC to play native DSD under Linux using MPD, you need to patch in this line and recompile your kernel.

Good work. Thanks!

 

[amirm]

Thanks for doing that.

Just one question, why the patch is needed?

What i read is that just the Support of DSD512 is added to the Kernel because the Topping uses the Big Endian coding.

You can configure the dsd support over alsa and the mpd.conf.

Thanks so much. This is what makes Linux open source so awesome, the constant attention to issues by the community and patches going out to address bugs.

without this patch only DoP is supported. this patch ensures it supports native dsd up to dsd512. see https://github.com/lintweaker/xmos-native-dsd

Hi Yue :

Does it support the DX7s ? Just ordered ...

I think a more detailed view says there is no need to practice in such a difficult mission as compiling the kernel. To PCM 192 kHz it goes via Toslink, which does not go according to the Topping manual at all. It's native to USB. The former version of the kernel and mpd.conf do without any changes to the system.

mpd.conf has a remnant .txt attachment, just to put it in the attachment

Do I read git right that this made it into 4.18?
