Comment 106 for bug 1516025

can you post the output of alsa-info.sh for the patched driver

https://wiki.ubuntu.com/PulseAudio/Log

can you post the pulseaudio vebose log

after select 2.1 profile, play stereo

you should see "LR4 filter enabled" in pulseaudio log

it is not clear alsa lib will pick up which channel map when both are available

    { .channels = 4,
   .map = { SNDRV_CHMAP_FL, SNDRV_CHMAP_FR,
     SNDRV_CHMAP_LFE, SNDRV_CHMAP_LFE } },
 { }

      { .channels = 6,
         .map = { SNDRV_CHMAP_FL, SNDRV_CHMAP_FR,
                 SNDRV_CHMAP_RL, SNDRV_CHMAP_RR,
                  SNDRV_CHMAP_FC, SNDRV_CHMAP_LFE } },

for using three jacks for external 5.1

do line out profile and speaker profile still work since pulseaudio assume headphone jack must exist ?
