Snakeoil Forums - Activate native DSD + Driver Intel 7265 wifi card

Hi, I am testing snakeoil in a DELL Latitude 3550 notebook, waiting to buy an intel NUC, I use it for my dsd library and as a roon server.

Anyone give me instructions to activate native dsd support?
Is there any way to use an Intel 7265 wireless card?

I am forced to stay at home and have run out of network cables.

Thank you!

I'll see if I can build a kernel later this weekend for Wifi. You do have to manually register to your SSID via the command line though.

As for native DSD, if your DAC is in one of the supported list, native DSD will work straight away. However, if not, you need to use a special kernel, and some tweaks. As this is still under testing, it's only available in the activated edition. If your DAC is based on Combo384 or Amanero (sp?), chances are, it will not work though. You can refer to this wiki article for more info.

Hello,
thanks, I made a donation last night and now I have the protected version.

I loaded the custom DSD kernel, and with the lsusb command I found the ID of my USB dac. It is a Luxman DA-06.
I tried the various settings for the native dsd but only noise comes out of the speakers. I can collaborate if you tell me what to do. With Lubuntu 18.04.4 the native DSD goes without doing anything, but I can't install the Kernel RT, so I went back to Snakeoil which seems more suitable to me.
Currently I would have these requests if possible:
1. The LCD backlight always stays on, can I turn it off?
2. Is it possible to spin the mechanical hard disk? I saw another user request, I followed what you suggested but the disk remains on.
3. Thanks for the wifi kernel as soon as you can build it!
4. I tried to configure exFAT, "sudo apt install exfat-fuse exfat-utils". But exFAT partitions still don't work.

5. Idea! You could put a command on your site to measure latency with snakeoil os and how to measure with other Linux or with Windows 10.
It would add value to your work and be one more reason to use your Linux distribution.

Thank you!

Can you make sure you set the ALSA volume to 100%? It may not be set properly in Snakeoil. The "Max volume" button don't always work so you might need to go to SSH, and run "sudo alsamixer" and manually do this.
If you're using the latest version of Snakeoil, you'll only need to do this one. The settings will be restored automatically on reboot (provided you shut down the computer gracefully).

LCD backlight of the DAC? Or PC monitor?

The problem with these commands is it's not universal. i.e. it all depends on the firmware on the HDD. Mechanical drives also tends to sound worse, a SSD is still the best option (costs have come down considerably, but still high) so ...

Supposed to do this last weekend, but I binged on "Attack On Titan" anime.. Once I started it, just can't stop.. Blush

Sorry. Hopefully will get to it soon.

SSH into the computer, and run "sudo dmesg" after you tried to mount a ex-fat partition. What errors are shown?

The reason for not having that is because this is a "relative" measurement, i.e. there is no set reference to compare the measurents against one and other. for example I may have a machine with 200 nanosecond latency, but your system with 1 microseconds sounds better than mine (1 microsecond is equal to 1000 nanoseconds). There are other factors at work, and because I don't understand this fully, there's no meaningful way to plot this.

Also, Windows latency is a measured of DPC calls. In a way that is still a queue. AFAICT linux RT scheduling is a lower level implemention. When the system is set to run in RT, and a process is set to the RT scheduler, when the process needs to run something, the OS is obligated to do so immediately. The time difference of when the process wants to excute, to the moment the instruction is actually executed is the latency we are measuring in cyclic test. Although this is better than Windows implemention (IMO), there are still alot of variables involved - the USB hardware you're using (hardware latency), quality of power delivery, presense of electrical/mangnetic noise, earth grounding implementation, and many more.

Main reason why Snakeoil is so flexible. You have the power to literally change everything possible on the PC side, some will have profound effects on sound reproduction, others will have none. It's all pretty system and audiophile dependent.

Hi,

DSD:root@roon:~# alsamixer
cannot open mixer: No such file or directory

LCD:
I would turn off the LCD screen's light of my notebook. It's become blank (black) but non turn off the rear LCD light.

WiFi:
I ordered a lan cable fro Amazon Wink

Thankyou

Run it as "sudo alsamixer"

I'm not entirely sure if this will work with the current kernel to be honest. Can you try this:

Code:
sudo su -c 'echo "0" > /sys/devices/virtual/[b]backlight[/b]/acpi_video0/brightness

And see if there are any errors? If no, does the backlight turn off after a while?

Hi,
the message is the same:

roon@roon:~$ sudo su -c 'echo "0" > /sys/devices/virtual/backlight/acpi_video0/brightness

After running the command that symbol remains and I have to press ctrl + C to return to the prompt.

Ok the Alsa mixer appeared, I tried all the combinations with 100% volume not working.

The backlight directory does not exist inside virtual. Wink

What do you say, you give up? Smile

That means the kernel doesn't have the necessary ACPI driver installed... Hopefully I can get a new kernel up with all ACPI bells and whistles... Days like this I hope I can dedicate more time to get the kernel site up and running.. Sad
