This can happen for two reasons: 1) The driver simply does not support this. 2) The driver is not able to automatically work out the model of your soundcard. If the latter is the problem you can potentially fix the issue by specifying the specific model via a setting in /etc/modprobe.d/ for the snd-hda-intel driver. Your codec (ALC662) has several models listed here: http://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio-Models.txt It is very much worth trying the different models manually, as the correct model may not be automatically detected correctly. If a model is found that gives you a fuller amixer -c0 output, then PA should hopefully be able to pick them up and use them. You will have to make sure that the model= setting only applies to your sound card itself and not the HDMI sound output (which also uses the snd-hda-intel driver). I think there is some magic in the modprobe.d file that achieves this). But either way, this is sadly not something we can fix in PulseAudio itself. It's something that needs to be addressed at a kernel level in alsa. I suggest liaising with RHEL bugzilla and perhaps posting to alsa-devel mailing list directly if you are confident enough in taking the issue forward yourself. Otherwise your support contract with RHEL will likely allow them to pursue the issue on your behalf (tho' I won't pretend to know much about the technical details here!!). All the best and if you need any further advise etc, please feel free to leave further comments. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
