How can I fix having to type alsa force-reload after each startup?

I am using Ubuntu 16.04 and try connect SOYTO SY733MV Black/Blue (USB-Headphones),

$ lsusb - show next:

...    
Bus 003 Device 007: ID 8086:0808 Intel Corp. 
...

and in /var/log/kern.log show next error [snd-usb-audio: probe of 3-2:1.0 failed with error -16] :

[34545.631107] usb 3-3: Product: USB 2.0 Hub
[34545.632062] hub 3-3:1.0: USB hub found

[34545.889443] snd-usb-audio: probe of 3-2:1.0 failed with error -16  

I fixed error above performed next action:

1) updated alsa-base.conf

$ sudo nano/etc/modprobe.d/alsa-base.conf

options snd_usb_audio index=auto
options snd_hda_intel index=2,3

2) unplugged USB headphones and execute next:

$ sudo alsa force-reload  

After plugging USB headphones show next log:

$ dmesg

3) set next in updated alsa-base.conf

$ sudo nano/etc/modprobe.d/alsa-base.conf

options snd_usb_audio index=1
options snd_hda_intel index=auto

reboot system.

If this problem occurs after upgrading from Ubuntu 18.04 to 20.04, it's not a problem in alsa itself but in the timidity converter.

Disable timidity and you won't even need to force reboot alsa on startup

systemctl disable timidity
