Check the USB entry and figure out why pulseaudio thought it an audio device. (In reply to Takashi Iwai from comment #1) > Check the USB entry and figure out why pulseaudio thought it an audio device. When the phone connects, it asks which mode to use; I chose "file transfer". Maybe that makes two different USB connections. Anyway, here is what I see in the journal: Okt 24 22:54:34 i7g4x4a.site kernel: usb 1-9.1: new high-speed USB device number 11 using xhci_hcd Okt 24 22:54:34 i7g4x4a.site kernel: usb 1-9.1: New USB device found, idVendor=22d9, idProduct=2046, bcdDevice= 2.23 Okt 24 22:54:34 i7g4x4a.site kernel: usb 1-9.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Okt 24 22:54:34 i7g4x4a.site kernel: usb 1-9.1: Product: CPH2371 Okt 24 22:54:34 i7g4x4a.site kernel: usb 1-9.1: Manufacturer: OPPO Okt 24 22:54:34 i7g4x4a.site kernel: usb 1-9.1: SerialNumber: REDACTED Okt 24 22:54:34 i7g4x4a.site mtp-probe[8390]: checking bus 1, device 11: "/sys/devices/pci0000:00/0000:00:14.0/usb1/1-9/1-9.1" Okt 24 22:54:34 i7g4x4a.site mtp-probe[8390]: bus: 1, device: 11 was not an MTP device Okt 24 22:54:35 i7g4x4a.site kernel: mc: Linux media interface: v0.10 Okt 24 22:54:35 i7g4x4a.site kernel: usbcore: registered new interface driver snd-usb-audio Okt 24 22:54:35 i7g4x4a.site mtp-probe[8408]: checking bus 1, device 11: "/sys/devices/pci0000:00/0000:00:14.0/usb1/1-9/1-9.1" Okt 24 22:54:35 i7g4x4a.site mtp-probe[8408]: bus: 1, device: 11 was not an MTP device Okt 24 22:54:35 i7g4x4a.site systemd[4072]: Reached target Sound Card.

It looks like a feature. The phone seems exposing itself as a virtual USB-audio device only with MIDI device. Since it's a USB-audio card, PA tries to probe, but couldn't probe the PCM, hence gave up. |
After I had connected my Android 13 phone via USB and enabled file sharing, I noticed the syslog message: pulseaudio[6779]: Failed to load module "module-alsa-card" (argument: "device_id="2" name="usb-OPPO_CPH2371_VSERIAL-00" card_name="alsa_card.usb-OPPO_CPH2371_VSERIAL-00" namereg_fail=false tsched=yes fixed_latency_range=no ignore_dB=no deferred_volume=yes use_ucm=yes avoid_resampling=no card_propertie="module-udev-detect.discovered=1""): initialization failed. ("VSERIAL" is the redacted actual serial number of the phone)
