Pico audio pack with rpi pico w on circutit python - no audio

Hey folks,
i downloaded the adafruit-circuitpython-raspberry_pi_pico_w-de_DE-8.0.0-beta.4.uf2 to the pico w, then i flashed the example sketch with the pins adopted to the pico audio and after that i only hear noise on high gain and nothing on low gain.
Can someone help me?

audio = audiobusio.I2SOut(board.GP10, board.GP11, board.GP9)

tone_volume = 0.1  # Increase this to increase the volume of the tone.
frequency = 440  # Set this to the Hz of the tone you want to generate.
length = 8000 // frequency
sine_wave = array.array("h", [0] * length)
for i in range(length):
    sine_wave[i] = int((math.sin(math.pi * 2 * i / length)) * tone_volume * (2 ** 15 - 1))
sine_wave_sample = audiocore.RawSample(sine_wave)

while True:
    audio.play(sine_wave_sample, loop=True)
    time.sleep(1)
    audio.stop()
    time.sleep(1)

Try to add a DigitalOutput for GP22 and pull it high. This is the active-low mute-pin.

Hi! I suspect I’m having a similar problem, I’m also using the pico W. The C/C++ only uses two pins for Audio IO so I have:

data-pin, clock-pin-base and maybe a mute pin? I feel like I have tried every combination of pins this could be but I just can’t figure it out.

I used this those days…

sound = WavPlayer(0, 10, 11, 9, amp_enable=29)			# 0=DMA Channel, 1st=Clock (BCLK), 2nd=WSEL , 3rd=DataIN (DIN), mute=29
