Asus Xonar D1 sound card extremely silent

Hello everyone,

I recently installed Kali Linux on my Desktop PC (Dual Boot with Win 10). The problem I am facing now is my sound card which does work in Windows, but is extremely silent in Kali (roughly 60-80dB less than in Windows where I use the official driver from Asus). I have an Asus Xonar D1 sound card, which uses the kernel module snd_virtuoso under Linux. I hope that I'm not talking nonsense here by the way, I am relatively new to anything that goes deeper into the Linux system than GNOME. Nevertheless, the virtuoso module seems to be loaded correctly:

So I don't think it's a driver issue. Here is a list of my PCI devices:

Code:

root@kali:~# lspci 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:01.0 PCI bridge: Intel Corporation Xeon E3-1200/2nd Generation Core Processor Family PCI Express Root Port (rev 09) 00:14.0 USB controller: Intel Corporation 7 Series/C210 Series Chipset Family USB xHCI Host Controller (rev 04) 00:16.0 Communication controller: Intel Corporation 7 Series/C216 Chipset Family MEI Controller #1 (rev 04) 00:1a.0 USB controller: Intel Corporation 7 Series/C216 Chipset Family USB Enhanced Host Controller #2 (rev 04) 00:1c.0 PCI bridge: Intel Corporation 7 Series/C216 Chipset Family PCI Express Root Port 1 (rev c4) 00:1c.2 PCI bridge: Intel Corporation 7 Series/C210 Series Chipset Family PCI Express Root Port 3 (rev c4) 00:1c.3 PCI bridge: Intel Corporation 82801 PCI Bridge (rev c4) 00:1d.0 USB controller: Intel Corporation 7 Series/C216 Chipset Family USB Enhanced Host Controller #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation Z77 Express Chipset LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation 7 Series/C210 Series Chipset Family 6-port SATA Controller [AHCI mode] (rev 04) 00:1f.3 SMBus: Intel Corporation 7 Series/C216 Chipset Family SMBus Controller (rev 04) 01:00.0 VGA compatible controller: NVIDIA Corporation GK106 [GeForce GTX 660] (rev a1) 01:00.1 Audio device: NVIDIA Corporation GK106 HDMI Audio Controller (rev a1) 03:00.0 Ethernet controller: Qualcomm Atheros AR8151 v2.0 Gigabit Ethernet (rev c0) 04:00.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 41) 05:00.0 Multimedia audio controller: C-Media Electronics Inc CMI8788 [Oxygen HD Audio]

So my sound card seems to be recognized properly as well. Just in case you need to know, here is my uname -a:

Code:

root@kali:~# uname -a Linux kali 4.8.0-kali2-amd64 #1 SMP Debian 4.8.11-1kali1 (2016-12-08) x86_64 GNU/Linux

I did choose the correct sound card in GNOME settings, so that cannot be the problem.
When I set the volume fader all the way up to 150% in GNOME and turn my speaker's volume fader to maximum, I can barely hear the test sound in GNOME settings (for comparision, in Windows this would be so loud that my ears would hurt). So my question is if there is any possibility to change the master volume of my sound card so that its output power is roughly the same as in Windows. It did work fine with Ubuntu some years ago, so I think there will be a way to fix this issue. It could either be the Virtuoso module, Oxygen HD Audio module or PulseAudio service that takes the volume down like that, but I think it has something to do with Pulse. Any help is kindly appreciated.
Thanks in advance,
Sandtler
