Audio Array AM-C1 USB Microphone – Linux(Ubuntu, Linuxmint, and NixOS) Compatibility Issue (USB Bandwidth Capture Failure).md

Subject: Audio Array AM-C1 USB Microphone – Linux Compatibility Issue (USB Bandwidth / Capture Failure)

Dear Audio Array Support Team,

I am seeking assistance regarding an issue with an Audio Array AM-C1 microphone on Linux systems.

Device Information

  • Product: Audio Array AM-C1
  • USB ID: 0c76:1719
  • Operating System: NixOS 26.05 (Linux Kernel 6.18.35)
  • Audio Stack: ALSA + PipeWire 1.6.5
  • Desktop Environment: Cinnamon

Problem Description

The microphone is detected successfully by the operating system, but no input level, and audio capture fails when streaming starts. The issue manifests as:

  • Audacity hangs during startup whenever the AM-C1 is connected.
  • PipeWire detects the microphone but fails to start capture.
  • Direct ALSA recording produces continuous buffer overruns.
  • Android devices connected through USB OTG also fail to use the microphone.

Detection Results

The device enumerates correctly:

Bus 002 Device 008: ID 0c76:1719 Audio Array AM-C1 Device

ALSA detects the microphone:

card 2: Device [Audio Array AM-C1 Device], device 0: USB Audio [USB Audio]

PipeWire detects the microphone:

Audio Array AM-C1 Device Mono

USB Audio Descriptor

The microphone reports the following capabilities:

Format: S24_3LE
Channels: 1
Rates:
22050
24000
32000
44100
48000
88200
96000
176400
192000

Notably, the device appears to support only the S24_3LE audio format.

ALSA Hardware Parameters

FORMAT: S24_3LE
CHANNELS: 1
RATE: [22050 192000]

Attempts to record using standard formats such as S16_LE fail because only S24_3LE is reported as available.

ALSA Capture Test

Command:

arecord -D hw:2,0 -f S24_3LE -r 48000 -d 5 test.wav

Output:

overrun!!!
overrun!!!
overrun!!!

continuously until the recording terminates.

PipeWire Errors

spa.alsa: hw:2c: snd_pcm_start: Broken pipe
spa.audioadapter: can't send command 2: Broken pipe
pw.node: suspended -> error (Start error: Broken pipe)

Kernel Messages

The Linux kernel reports:

usb 2-1.5: cannot submit urb 0, error -28: not enough bandwidth

This message repeats whenever audio capture is attempted.

Troubleshooting Performed

  • Connected directly to motherboard USB ports (no hub).
  • Tested with Audacity and Tenacity.
  • Verified ALSA device detection.
  • Verified PipeWire source creation.
  • Tested multiple recording rates.
  • Confirmed microphone is detected but cannot successfully stream audio.

Questions

  1. Is the AM-C1 expected to work as a standard USB Audio Class device on Linux without proprietary drivers?
  2. Is there any firmware update available for the AM-C1?
  3. Are there known compatibility issues with Linux, Android, or EHCI/xHCI USB controllers?
  4. Does the device require a specific sample rate, USB controller type, or driver configuration?
  5. Can you provide official Linux compatibility guidance or troubleshooting procedures?

I would appreciate any technical documentation, firmware updates, or recommendations that may help resolve this issue.

Thank you for your assistance.

Kind regards,

Prateek Gautam Linux User / NixOS 26.05 Audio Array AM-C1 Owner
