not working in kali linux 2017.3

[Nicee1]

Hello there, I am currently using kali linux 2017.3 in my lenovo y50. **uname -a** Linux BlackjacK 4.14.0-kali1-amd64 #1 SMP Debian 4.14.2-1kali1 (2017-12-04) x86_64 GNU/Linux I tried running your script and it failed to enable my subwoofer. I have attached the following outputs after reading other issues here.

The output of Suboofer.py:

After running the script I tried these commands too:

systemctl --user disable subwoofer
 systemctl --user enable subwoofer
 reboot
 systemctl --user status subwoofer

But no luck. I got the same above output.

Hmm, see if amixer works in your terminal. If not, try sudo apt-get install alsa-tools in your terminal and show me what it says.

Error is OSError: [Errno 2] No such file or directory when Python tries to Popen (open the process) amixer = subprocess.Popen(["amixer", "-c", str(devId), "cget", "numid=22"], stdout=subprocess.PIPE, stderr=subprocess.PIPE). So, we're trying to see if amixer even exists/was installed in your Kali system.

I checked for amixer and it was not there.

I then installed it by the following command: sudo apt-get install libasound2 alsa-utils alsa-oss and got this:

I tried the script again but not worked. Thanks for your reply.

Yeah, that needs Python debug. I am sorry but I do not have the time these days. :[
