LEDC output not usable on lolin_c3_mini

The problem

LEDC output is not usable on the lolin_c3_mini. My configuration contains:

output:
  - platform: ledc
    pin: D6
    id: buzzer

but on boot, I get the following error:

[D][ledc.output:041]: Calculating resolution bit-depth for frequency 1000.000000
[D][ledc.output:046]: Resolution calculated as 16
[E][esp32-hal-ledc.c:60] ledcSetup(): No more LEDC channels available! (maximum 6) or bit width too big (maximum 14)

I have tried different GPIO pins, manually specifying the channel, and manually raising and lowering the frequency but no combination seems to work.

I suspect some of the issue is because the lolin_c3_mini has an on-board WS2812 which I have configured as an output with neopixelbus. However surely there is a way to get a single additional LEDC output working, even at low resolution. For what it's worth, I'm trying to use this ledc output as a rtttl buzzer output.
