[Solved] ALSA Sample Rate Conversion or PulseAudio headphone switch
I've tried a number of solutions to stop ALSA from automatically resampling 44.1Khz to 48Khz, and I have reached an impasse. Let me explain my reason. Yesterday, I noticed that Audacious used a ridiculous amount of CPU cycles when playing an MP3. My first searches brought me to a post inan Audacious forum thread that asked about the same problem. Dmix, I learned, automatically resamples any 44.1Khz audio if it finds that your card supports 48Khz. I could force dmix to a 44.1Khz rate but might find some problems when playing DVDs.
This must have bothered me at the time because I decided instead to install PulseAudio. It worked well. But it linked together my headphones/front panel audio and speakers. I couldn't switch between the two like I could with ALSA's headphone switch. In fact, using the headphone switch (via alsamixer -c 0) or any other alsamixer control muted all audio. Maybe, my searches suggested, explicitly setting a model for my snd-hda-intel driver would help. Per ALSA, my sound card uses the AD1989B codec. Looking in the ALSA documentation, the 6stack-dig model seemed the best choice: my Asus P6T motherboard offers six audio jacks and SPDIF output. This didn't work.
I give priority to quick switching between my headphones and speakers, so I decided to remove PulseAudio and forced dmix to use a 44.1Khz sample rate.
And then I tried to play a video on YouTube. I hear a consistent clipping or popping sound whenever I find Flash that uses sound. I've disabled dmix for now, but I'd like to see it return. How can I stop the popping sound and audio resampling? Alternatively, how can I make PulseAudio switch between my headphones and speakers?
I provide the output of ALSA's alsa-info.sh below.

Re: [Solved] ALSA Sample Rate Conversion or PulseAudio headphone switch
Regarding 44.1 vs 48 - just choose one. I have played with both, since my Acer Aspire laptop's snd-hda-intel chip can output both, and I can hear zero difference between them. 44.1 doesn't cause problems with movie playback.
I suggest you rename your ~/.config/audacious, to reset to a clean config. Also, you should google about your "Suggest a bigger bdl_pos_adj" error message.
Here's my current ~/.asoundrc for you to read, and try. For background, see thread.
I personally use alsa and nothing else. Not even esound - it is possible to compile XFCE without it.

Re: [Solved] ALSA Sample Rate Conversion or PulseAudio headphone switch
Thanks a lot. That ~/.asoundrc works just as I want. I stuck it in asound.conf to force the change on the other user of this machine; I removed some extraneous bits for initial testing. For reference, I print my current asound.conf below. (I guess that the fix has something to do with using the asym plugin?)

slave.pcm "dmixed"
}Also, that "Suggest a bigger bdl_pos_adj" message disappeared after I added enable_msi=1 to the options for snd-hda-intel.
Thanks again.
