Linux Creative sound blaster not detected fully
#1
Hello,

I am running Kodi-15.1 on a gentoo amd64 system which has a Creative Blaster soundcard. Unfortunately, Kodi only lists the default and 2.1 version of the sound card and does not list the 5.1 device.

The log does not list the surround5.1 device:

ALSA on the other hand does list the surround5.1 device:

My system details:

How can i get Kodi to list the surround 5.1 device?

Actually, please try to play something by choosing the default (@) and if this does not work the device the 2.1 device, set your speakers to 5.1 and post a log, here is a testsample for you:

See: https://github.com/xbmc/xbmc/blob/master....cpp#L1061

Thanks for the test file. I can confirm that with the default device (channels 5.1 set) all the 5.1 channels work successfully. However there are a couple of issues i noticed:

1. The Center speaker has a much lower volume compared to the Front Left and Front Rear speakers. If i do a speaker-test it is pretty loud. Something in kodi is reducing the volume. In Audio settings the output configuration is set as "Best Match" and "Maintain original volume in downmix is enabled".

2. The Rear left and right speakers seems to be swapped in the Test audio file compared with ALSA speaker test.

Code:
#speaker-test -Dsurround51:CARD=Live -t wav -c6

speaker-test 1.0.29

Playback device is surround51:CARD=Live
Stream parameters are 48000Hz, S16_LE, 6 channels
WAV file(s)
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 64 to 16384
Period size range from 16 to 16384
Using max buffer size 16384
Periods = 4
was set period_size = 4096
was set buffer_size = 16384
0 - Front Left
4 - Front Center
1 - Front Right
3 - Rear Right
2 - Rear Left
5 - LFE

Nope - nothing reduces volume.

So the volume reduction is coming from the test file? Anyway to fix this?

Use our DSP addons - available in kodi nightly.
