Rane SL-4 USB sound card

Rane SL-4 USB sound card

[Tuukka Pasanen]

Hello,
I've been hacking to get Rane SL-4 USB audio 
(http://dj.rane.com/products/sl4-for-serato-scratch-live) which have 4 
Input and 4 output channel to work with ALSA. After digging the lsusb 
and snoops I have separated endpoints for input (0x82) and output 
(0x06). They are just USB Isochronous I/O.
I have compiled kernel and tried to get USB-quirks to work with this but 
then I have to admit that even Reloop Play seems be very similar it 
doesn't do the trick (No error but card doesn't come up eather) nor 
using Ranel SL-1 approach which just shoots the error

[ 3555.009349] usb 1-5: Audio class v2 interfaces need an interface 
association

If I need interface association how to do that? Trying to adjust mixer 
values in mixer_maps.c.

If someone have a time to give some guidance if this doable with Quirks 
or do I have to write some more specific driver? I attach lsusb below here.
HID device seems to be adjusting buffer size and 48 Khz and 96 Khz output.

The interface association descriptor should have been provided by the firmware.

Anyway, try the following quirk:

{
	USB_DEVICE(0x1cc5, 0x000f),
	.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 = 1,
				.type = QUIRK_AUDIO_STANDARD_INTERFACE
			},
			{
				.ifnum = 2,
				.type = QUIRK_AUDIO_STANDARD_INTERFACE
			},
			{
				.ifnum = -1,
			}
		}
	}
},

Hello,
Thanks you for you reply. That did the trick almost. It only gives 
sysdefault with two channels and error:

[176317.418587] usb 1-5: parse_audio_format_rates_v2(): unable to 
retrieve number of sample rates (clock 5)

I figured out this kind of QUIRK which seems to be working (go to test 
tomorrow more). I would go with first quirck as it's looking simpler but 
I can't add rates to it?

So it doesn't actually conform with the audio class.

Hmm, the descriptors claim it uses S24_LE ...

Do all channels work?
Does it correctly switch between 48/96 kHz?
Is it possible to use different rates for playback/capture?

Hello,
Thank you that 24_LE. I'll test tommorrow and find answers to there 
questions. I'll think that 48/96 won't work because it seems to be 
behind that HID.. but that this after I get sound out and in.

Hello,
I've tested Quirck and it worked (at least channels 1-2 input/output) 
fine when changed S24_LE. Problem is that currently it doesn't have 
Mixer so pulseaudio or jackd can't see it without .asoundrc. I digged 
little bit mixer_map.c but didn't get it working.

Sincerely,
Tuukka

According to the descriptors, it does not have mixer controls.
Does the Windows driver have mixer controls that affect the hardware?

That should make no difference.

Hello,
No it doesn't. Hmm... I got to examine this more because even Yast2 cant 
see this or alsaconf..

Hello,
More digging on this. Pulseaudio and jackd (portaudio) are supporting 
24_3LE (Tree byte) that is why they didn't work with 24_LE. Is 24_LE 
just 32_LE (4 bytes) and first byte is just zeroed? If that is so I can 
use 32_LE and applications just work?

Sincerely,
Tuukka

Sorry, S24_LE is completely wrong; that should have been S32_LE.
