Hello Alan, Thanks for you attention!
I think just that this webcam. Hardware for each function. The microphone works fine, see the results below: I think there is a particular way to initiate this webcam microphone, and this particular form is used in windows and later on Linux. If I start windows and use a webcam, when I restart the computer in the microphone Linux it works perfectly! lsusb Bus 002 Device 003: ID 0471:2034 Philips cat /proc/asound/cards 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0xf0500000 irq 22 1 [Camera ]: USB-Audio - USB Video Camera USB Video Camera at usb-0000:00:1d.7-2, high speed amixer -c 1 Simple mixer control 'Mic',0 Capabilities: cvolume cvolume-joined cswitch cswitch-joined Capture channels: Mono Limits: Capture 0 - 65535 Mono: Capture 61602 [94%] [-128.00dB] [on] Simple mixer control 'Auto Gain Control',0 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [off] lshal (only part) udi = '/org/freedesktop/Hal/devices/usb_device_471_2034_noserial_if1' info.linux.driver = 'uvcvideo' (string) info.parent = '/org/freedesktop/Hal/devices/usb_device_471_2034_noserial' (string) info.product = 'USB Video Interface' (string) info.subsystem = 'usb' (string) info.udi = '/org/freedesktop/Hal/devices/usb_device_471_2034_noserial_if1' (string) linux.hotplug_type = 2 (0x2) (int) linux.subsystem = 'usb' (string) linux.sysfs_path = '/sys/devices/pci0000:00/0000:00:1d.7/usb2/2-2/2-2:1.1' (string) usb.bus_number = 2 (0x2) (int) usb.can_wake_up = false (bool) usb.configuration_value = 1 (0x1) (int) usb.device_class = 239 (0xef) (int) usb.device_protocol = 1 (0x1) (int) usb.device_revision_bcd = 0 (0x0) (int) usb.device_subclass = 2 (0x2) (int) usb.interface.class = 14 (0xe) (int) usb.interface.number = 1 (0x1) (int) usb.interface.protocol = 0 (0x0) (int) usb.interface.subclass = 2 (0x2) (int) usb.is_self_powered = false (bool) usb.linux.device_number = 3 (0x3) (int) usb.linux.sysfs_path = '/sys/devices/pci0000:00/0000:00:1d.7/usb2/2-2/2-2:1.1' (string) usb.max_power = 98 (0x62) (int) usb.num_configurations = 1 (0x1) (int) usb.num_interfaces = 4 (0x4) (int) usb.num_ports = 0 (0x0) (int) usb.product = 'USB Video Interface' (string) usb.product_id = 8244 (0x2034) (int) usb.speed = 480.0 (480) (double) usb.vendor = 'Philips' (string) usb.vendor_id = 1137 (0x471) (int) usb.version = 2.0 (2) (double) udi = '/org/freedesktop/Hal/devices/usb_device_471_2034_noserial_if2_alsa_capture_0' alsa.card = 1 (0x1) (int) alsa.card_id = 'USB Video Camera' (string) alsa.device = 0 (0x0) (int) alsa.device_file = '/dev/snd/pcmC1D0c' (string) alsa.device_id = 'USB Audio' (string) alsa.originating_device = '/org/freedesktop/Hal/devices/usb_device_471_2034_noserial_if2' (string) alsa.pcm_class = 'generic' (string) alsa.type = 'capture' (string) info.capabilities = {'alsa'} (string list) info.category = 'alsa' (string) info.parent = '/org/freedesktop/Hal/devices/usb_device_471_2034_noserial_if2' (string) info.product = 'USB Audio ALSA Capture Device' (string) info.subsystem = 'sound' (string) info.udi = '/org/freedesktop/Hal/devices/usb_device_471_2034_noserial_if2_alsa_capture_0' (string) linux.device_file = '/dev/snd/pcmC1D0c' (string) linux.hotplug_type = 2 (0x2) (int) linux.subsystem = 'sound' (string) linux.sysfs_path = '/sys/class/sound/pcmC1D0c' (string) Thanks for you help!
