I am not able to get sound out of the SPDIF output of M-Sound Fast Track Pro. Kodi does not recognize all possible audio outputs in Settings->System->Audio output. Using "aplay -Dplughw:2,1 /var/tmp/test.wav" works, but this sound output is not possible to select in Kodi.

Please if you are at it - post the complete output of speaker-test -c 2 -D plughw:2,1

breisladdmeister · 2015-12-21, 15:20

Thank you for your quick reply.

$ LC_ALL=C speaker-test -c 2 -D plughw:2,1

speaker-test 1.0.29

Playback device is plughw:2,1
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 96 to 174762
Period size range from 48 to 87381
Using max buffer size 174760
Periods = 4
was set period_size = 43690
was set buffer_size = 174760
0 - Front Left
1 - Front Right
Time per period = 5.526839
0 - Front Left
^C 1 - Front Right
Time per period = 0.578304

And this generates noise in the speakers. No success with Kodi.

Good - yeah. Your driver is broken, broken, broken ... you won't be happy with it, here a kodi patch:

Can you build kodi from source and apply this patch?

breisladdmeister · 2015-12-21, 15:41

Thank you for your reply. I will consider building Kodi from source. But is the real source of this problem snd_usb_audio kernel driver?

I have enabled 24bit/96kHz with:
$ cat /etc/modprobe.d/fast-track-pro.conf
# This will put the FastTrack Pro at device number 2 with 24bit mode, max. 48kHz sampling mode,
# 2 inputs and 4 outputs. According to the patch, the possible values for the device_setup
# parameter are the sum of the following numbers:

# 0x01 : use the device_setup parameter, always needed
# 0x02 : enable digital output (channels 3,4)
# 0x04 : use 48kHz-96kHz sampling rate, 8-48 kHz if not used
# 0x08 : 24bit sampling rate
# 0x10 : enable digital input (channels 3,4)

options snd_usb_audio vid=0x763 pid=0x2012 device_setup=0xF index=2 enable=1

The problem is your sound card driver. Try toe remove all those custom probes and post me a logfile without those, please.

24 bit sampling rate <- what is that? (the comment is most likely wrong) - please remove all those and post another kodi.log

breisladdmeister · 2015-12-21, 17:50

After removing additional options to snd_usb_audio:
kodi.log

Still no sound from Kodi, but "speaker-test -c 2 -D plughw:1,1" works.

Why is Kodi only enumerating CARD=Pro,DEV=0 and not CARD=Pro,DEV=1?

**fritsch** · (This post was last modified: 2015-12-21, 21:22 by fritsch.)

Kodi won't have sound as your driver is broken and does not tell us any supported format ...
it does - one is the analog the other the spdif

You only chance is to add the patch - I don't plan to workaround broken drivers by guesswork.

**fritsch** · 2015-12-21, 21:23

With patch it looks okay (that's with the patch, right?)

To workaround, you can try something like this:

You need to find your device string like "FastTrack Pro" or something.
