Re: [alsa-devel] Zoom R16
Can't seem to compile 3.11 or 3.12 for the distro I am using (AVLInux)... tested it in Ubuntu Studio 13.10 and the quirk didn't seem to have any effect. The output of lsusb is the same, but the device doesn't show up as a sound card.

I was able to compile 3.11.9 for AVLinux. The quirk does not work, dmesg returns this:

Actually, after a few more tries it DOES work for capture... but fails on playback just as it did with my original quirk.
Here are logs from a playback-only attempt. Looks like there are some packetsize errors and failing to set sample rate for playback

It seems that ALSA is trying to initialize the device at 32-bit integer little endian despite having the .formats set to SNDRV_PCM_FMTBIT_S24_LE in the quirk. The device is 24-bit integer only. Other devices I have initialize properly at 24 bits.
Perhaps capture works because the device is running at 24 bits and sending info into the 32 bit driver... and playback fails because the driver is trying to force the device to operate at 32 bits, which it is incapable of???
Is there another/better way to force the bitrate to 24 bits?

Do you mean the 24bit physical size, i.e. each frame is packed in 3 bytes? If so, you used a wrong format. SNDRV_PCM_FMTBIT_S24_LE is for 24bit format packed in 32bit frame. If you need a 3-bytes frame, use SNDRV_PCM_FMTBIT_S24_3LE instead.

With it set to 3LE format it fails on both capture and playback, and is still trying to initialize at 32 bits for both.
Any other formats I could try? On Dec 6, 2013 11:25 AM, "Takashi Iwai" tiwai@suse.de wrote:

I am still working on trying to get the R16 to work for playback. The problem is that no matter what .formats setting I use, ALSA sets the R16 to 32 bit LE (the R16 operates at 24 bit integer only). This is fine for capture as the R16 is sending a 24 bit stream into a 24-in-32 ALSA capture... but for playback, the 32 bit ALSA stream chokes when it hits the 24 bit integer R16 device.
So, the main question is how do I force ALSA to initialize this device at 24 bit integer?
For the record, here is the quirk that I am working with (working for capture, recognized for playback but crashes on data). Thanks for any suggestions.

And are you sure that you patched correctly? For example, if you change the available rates in addition, does the patched kernel also show the same change?

Isn't the answer in Takashi's original reply...?

Many USB devices have this...

instead. That would apply for capture also. Or is that what you

trying?

Just verified only 96000 shows as available when I omit the other rates from the quirk.
FWIW, other users at linux audio forum are seeing the same result of ending up with S32_LE regardless of .formats setting.
But with capture working, wondering if it is possible that the S32_LE is indeed the correct format, and the playback problem is something else... one user is investigating possible wrong UAC version. There are get/set sample rate errors on playback as well.
Thanks for your help, any ideas are appreciated!

Just verified only 96000 shows as available when I omit the other rates from the quirk.
Then try to add more format bits there and see whether the proc file shows them, too. If the proc file doesn't show, debug why it doesn't do so. The proc output (in proc__dump_substream_formats()) is basically a collection of audioformat list, which is added directly by create_fixed_stream_quirk().
At this moment, it doesn't matter what jack shows. The only thing to be checked is whether the driver takes the value as is or not.
FWIW, other users at linux audio forum are seeing the same result of ending up with S32_LE regardless of .formats setting.
Do you mean in proc or jack output?
But with capture working, wondering if it is possible that the S32_LE is indeed the correct format, and the playback problem is something else...
Possibly. But you must figure out what you're debugging at first.
