Subject: Sound on a Thinkpad 1720i

I have an IBM i series 1720i Thinkpad running 3.3-STABLE #7.

I decided that I would like the sound to work.  This laptop has a Crystal
CS4232.  Looking in the docs, it looked like pcm0 would be the easiest
to use (and I had tried with no success to use snd0).

Here are the relevant lines from a boot:

... try to identify the yamaha
pcm0 at 0x530 irq 5 drq 1 flags 0xa213 on isa
mss_attach <mss>0 at 0x530 irq 5 dma 1:3 flags 0xa213

Here's the config line from the kernel config file:
device pcm0 at isa? port ? tty irq 5 drq 1 flags 0x13

The BIOS config lists the following:
  SB    220-22F
  WSS   530-538
  Adlib 388-38F
  MPU   330-331
  CTRL  120-121
  DMA A 1
  DMA B 3
  IRQ   5

Trying snd1 leads to the message:
pcm1: unit not configured, perhaps you want pcm0 ?

Trying snd0 (cat file.au >/dev/audio) leads to it just sitting there (no
sound out).  When I give up and interrupt the cat, I get
tsleep returns 4

The volume control is up; beeps work fine.

Any suggestions?

Kenneth
