as you previously stated :

which i then followed up with a post that had the information.
then you said:

so i posted it again.

then, apparently you're now upset that i did that.

regardless, we seem to have gotten past that.

ok. now i get it .  i was confused by the link to the web-page you posted. it seemed to indicate that you could get aplay to perform the conversion by specifying the format with the -f option. clearly it can't do that.

very helpful. i didn't know you could do that.  i guess aplay just plays the bytes.

Interesting.  I absolutely tried that before, as per the instructions in your previous post, and it didn't help in iceweasel. I suspect i forgot to restart iceweasel.

so now that _does_ fix  the aplay problem, both on the command line and in iceweasel !

excellent !!

this is very interesting, because if aplay can't convert the file format, how is it getting converted ??

also, i forgot to mention that I also put the following in  /etc/modprobe.d/alsa/base.conf

options snd slots=snd_usb_audio,snd_hda_intel,snd_hda_intel
options snd_usb_audio index=0 vid=0x08bb pid=0x2704


My understanding is that this will cause the modules to be loaded in a fixed order which would make the HW designations consistent.  I believe now that's unnecessary since i'm now using "card A2" in my .asoundrc file.

Thank you,

Brian
