Thank you for your help.

I had already tested without the single_cmd=1 option, and
the only difference I see is the " azx_get_response timeout,
switching to polling mode" warning. Probably related is the
fact that I have never seen an IRQ 22. 

from proc/interrupts :

 22:          0          0   IO-APIC-fasteoi   uhci_hcd:usb6, HDA Intel

For your information, the initial log shows the following :

As i said, mplayer outputs the sound correctly, this is what
it logs :
