Add Volume Limiter Support

[duckman]

Description

Would love to be able to disable the volume limiter on the SteelSeries Arctis Nova 7. Looks like there is a function in the device file but I don't see a way to execute it.

Headset Name

SteelSeries Arctis Nova 7

Looks like there is a function in the device file but I don't see a way to execute it.

Yeah the guy implementing it found it probably during his WireShark Session but didn't implement it as headsetcontrol currently has no command for that.

You can feel free to add one (not really complicated, you can just copy the code for send_microphone_volume):

• Add here a new funtion, similar to send_microphone_volume:

  HeadsetControl/src/device.h

  Line 324 in f64ac48

  int (*send_microphone_volume)(hid_device* hid_device, uint8_t num);

• In the Arctis 7 file, reference the function you saw here:

  HeadsetControl/src/devices/steelseries_arctis_7.c

  Line 40 in f64ac48

  device_arctis.send_sidetone = &arctis_7_send_sidetone;

• Also in device.h add a capbability just calling it CAP_VOLUME_LIMITER :

  HeadsetControl/src/device.h

  Line 38 in f64ac48

  CAP_MICROPHONE_VOLUME,

• Now you just need to implement the parameter in main.c:
  • Add an option here { "volume-limiter", required_argument, NULL, 0 },

    HeadsetControl/src/main.c

    Line 529 in f64ac48

    { "microphone-volume", required_argument, NULL, 0 },

  • Handle that option here, simply copy the microphone volume code and rename things (and create a variable on top):

    HeadsetControl/src/main.c

    Lines 706 to 712 in f64ac48

    	} else if (strcmp(opts[option_index].name, "microphone-volume") == 0) {
    	microphone_volume = strtol(optarg, &endptr, 10);
    	if (*endptr != '\0' || endptr == optarg || microphone_volume < 0 || microphone_volume > 128) {
    	fprintf(stderr, "Usage: %s --microphone-volume 0-128\n", argv[0]);
    	return 1;
    	}

  • Also here:

    HeadsetControl/src/main.c

    Line 806 in f64ac48

    { CAP_MICROPHONE_VOLUME, CAPABILITYTYPE_ACTION, &microphone_volume, microphone_volume != -1, {} },

  • Then call your new function in handle feature:

    HeadsetControl/src/main.c

    Line 301 in f64ac48

    case CAP_MICROPHONE_VOLUME:

Feel free if you struggle somewhere

I created a pull request for some missing features of the Steelseries Artic Nova 7:

• microphone mute led brightness
• microphone volume
• volume limiter

@duckman all the feature for your headphones will be included with my pull request

You sir are a gentleman and a scholar. I'll try it out tonight.
