PulseAudio low quality output

Having recently gotten a pair of bluetooth headphones, I've been messing with the bluetooth module. However, now I've gone and messed up Pulse, but I'm not at all sure how.

Succinctly put, audio output through my front panel headphones jack sounds like it's encoded at 32kbps and 12khz. Audio through the rear panel works fine, though.

This is all I can think of in terms of diagnostic data to share:

[patrick@blendtec ~]$ aplay -l | grep card
card 0: HDMI [HDA Intel HDMI], device 3: HDMI 0 [HDMI 0]
card 0: HDMI [HDA Intel HDMI], device 7: HDMI 1 [HDMI 1]
card 0: HDMI [HDA Intel HDMI], device 8: HDMI 2 [HDMI 2]
card 1: PCH [HDA Intel PCH], device 0: ALC892 Analog [ALC892 Analog]
card 1: PCH [HDA Intel PCH], device 1: ALC892 Digital [ALC892 Digital]

[patrick@blendtec ~]$ lsmod | grep hda
snd_hda_codec_hdmi     49263  1 
snd_hda_codec_realtek    63196  1 
snd_hda_codec_generic    63087  1 snd_hda_codec_realtek
snd_hda_intel          26387  4 
snd_hda_controller     26938  1 snd_hda_intel
snd_hda_codec         112621  5 snd_hda_codec_realtek,snd_hda_codec_hdmi,snd_hda_codec_generic,snd_hda_intel,snd_hda_controller
snd_hwdep              17244  1 snd_hda_codec
snd_pcm                88785  4 snd_hda_codec_hdmi,snd_hda_codec,snd_hda_intel,snd_hda_controller
snd                    73436  16 snd_hda_codec_realtek,snd_hwdep,snd_timer,snd_hda_codec_hdmi,snd_pcm,snd_hda_codec_generic,snd_hda_codec,snd_hda_intel
soundcore              13031  2 snd,snd_hda_codec

[patrick@blendtec ~]$ cat /proc/asound/card*/codec* | grep Codec
Codec: Intel Haswell HDMI
Codec: Realtek ALC892

Anyone have an idea? I tried every single option in the "Audio Quality" section in the wiki, and none of them were effective.

Re: PulseAudio low quality output

Post the config files of pulseaudio (/etc/pulse/*) and ALSA (/etc/asound, ~/.asoundrc or similar) and everything you might have changed. The commands you posted contain no information with which anyone can do anything. Output of

pulseaudio -vv

might also help.
