Problem with Rog Delta S Wireless

[bagou4502]

Greetings,

I am posting this issue here since I haven't found a solution in forums yet.

I am facing an problem with my Rog Delta S Wireless headset when using Linux with Gnome. The volume control doesn't function correctly. Setting the volume to < 95% keeps the sound at 0 in alsamixer. When I set it to 95%, alsamixer shows 50%, and 100% corresponds to 100% in alsamixer.

This issue occurs specifically with this headset in both 2.4GHz and Bluetooth modes. I have already tried using another Rog Delta S Wireless headset, but the same problem persists. Additionally, I tested it on multiple computers running Fedora, Ubuntu 22.04 and 23.04, Debian 11 and 12, as well as ZorinOs 16.2 and 16.3, and encountered the same problem on all of them.

Here is a video demonstrating the issue: https://www.youtube.com/watch?v=-OuKtLt5U1k

Unfortunately, I am uncertain whether this problem originates from the Gnome volume system or AlsaMixer.

I am hopeful that someone can assist me with this matter. Thank you for your help.

OMG. I was wondering why this headset is not working under linux. It is detected, mic works, alsa shows it, no issues, just no sound :D But it does work - only when the volume is set to 99 %. Thanks for the tip :)

In my case: at 98 % or lower no sound, 99 % sound is ok, at 100 % it breaks my eardrums.

Show amixer -c 0 contents for the mentioned headset (replace zero with the correct card number). It looks like a driver issue.

set to 98 %, 99 % and last one to 100 %

The dB values reported by device are totally bogus:

numid=4,iface=MIXER,name='PCM Playback Volume'
  ; type=INTEGER,access=rw---R--,values=2,min=0,max=128,step=0
  : values=62,62
  | dBminmax-min=-0.50dB,max=0.00dB

The correct values are like:

numid=6,iface=MIXER,name='Mic Capture Volume'
  ; type=INTEGER,access=rw---R--,values=1,min=0,max=45,step=0
  : values=45
  | dBminmax-min=-54.00dB,max=-9.00dB

It seems that the device does not follow USB Audio standard so the driver should apply a workaround. I would report this to linux-sound@vger.kernel.org with USB IDs (amixer -c 3 info or lsusb | grep ROG should be enough).

Thanks, will try. Hope somebody will fix it as in most of the cases people are sending patches :)
Adding details here as well, so google will find it.
