How do I find out? Can I look it up in a log file, or do I actually look at
the text on the chips ?

The card and chip are these according to alsamixer:
Card: Sound Fusion CS46xx                                                 
                         Chip: Cirrus Logic CS4294 rev 5,Cirrus Logic
CS4294 rev 5,Cirrus Logic CS4294 rev 5                 &#9474;

The other limited resource of cs46xx is SRC

     snd_printk (KERN_ERR "dsp_spos: no free PCM channel\n");

     if (ins->nsrc_scb >= DSP_MAX_SRC_NR) { 
         snd_printk(KERN_ERR "dsp_spos: to many SRC instances\n!");
