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:

2) Short (0.15 sec) .wav @ 44.1 kHz:
https://sites.google.com/site/zoomr16linux/technical-information/usbsnoop2.log.bz2?attredirects=0
https://sites.google.com/site/zoomr16linux/technical-information/short.wav?attredirects=0&d=1
It would be fun to get this device working with Linux. I'd appreciate a lot
if someone could help me out.
Regards,
Jani
