Hello all,
I've been trying to make Zoom R16 multi track recorder / audio interface / control surface working with Linux without any success. I've tried this quirk, but it usually just hang the unit:
{ /* ZOOM R16 in USB 2.0 mode */ USB_DEVICE(0x1686, 0x00dd), .driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) { .ifnum = QUIRK_ANY_INTERFACE, .type = QUIRK_COMPOSITE, .data = (const struct snd_usb_audio_quirk[]) { { .ifnum = 0, .type = QUIRK_AUDIO_STANDARD_INTERFACE }, { .ifnum = 1, .type = QUIRK_AUDIO_STANDARD_INTERFACE }, { .ifnum = 2, .type = QUIRK_AUDIO_STANDARD_INTERFACE }, { .ifnum = 3, .type = QUIRK_MIDI_STANDARD_INTERFACE }, { .ifnum = -1 }, } } },
This one doesn't freeze it, but it neither works. No sound with playback.
{ /* ZOOM R16 in USB 2.0 mode */ USB_DEVICE(0x1686, 0x00dd), .driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) { .ifnum = QUIRK_ANY_INTERFACE, .type = QUIRK_COMPOSITE, .data = (const struct snd_usb_audio_quirk[]) { { .ifnum = 0, .type = QUIRK_AUDIO_STANDARD_INTERFACE, }, { .ifnum = 1, .type = QUIRK_AUDIO_FIXED_ENDPOINT, .data = &(const struct audioformat) { .formats = SNDRV_PCM_FMTBIT_S24_3LE, .channels = 2, .iface = 1, .altsetting = 1, .altset_idx = 1, .attributes = UAC_EP_CS_ATTR_SAMPLE_RATE, .endpoint = 0x03, .ep_attr = 0x01, .maxpacksize = 0x6c, .rates = SNDRV_PCM_RATE_44100 | SNDRV_PCM_RATE_48000 | SNDRV_PCM_RATE_88200 | SNDRV_PCM_RATE_96000, .rate_min = 44100, .rate_max = 96000, .nr_rates = 4, .rate_table = (unsigned int[]) { 44100, 48000, 88200, 96000 } } }, { .ifnum = 2, .type = QUIRK_AUDIO_STANDARD_INTERFACE }, { .ifnum = 3, .type = QUIRK_MIDI_STANDARD_INTERFACE }, { .ifnum = -1 }, } } },
I attached the lsusb -v output. There are couple usb snoop logs.
1) The other, not so great OS plays new device found sound @ 96 kHz: https://sites.google.com/site/zoomr16linux/technical-information/usbsnoop.lo...
2) Short (0.15 sec) .wav @ 44.1 kHz: https://sites.google.com/site/zoomr16linux/technical-information/usbsnoop2.l... https://sites.google.com/site/zoomr16linux/technical-information/short.wav?a...
It would be fun to get this device working with Linux. I'd appreciate a lot if someone could help me out.
