Memory problems are back with SB Live!

["Chris Rankin" <rankincj@yahoo.com>]

Hi,

My box has now accumulated almost 3 weeks of uptime,
and so the ALSA memory problem is back again:

$ aplay /usr/lib/sounds/jungle_exit.wav 
Playing WAVE '/usr/lib/sounds/jungle_exit.wav' :
Signed 16 bit Little Endian, Rate 22050 Hz, Stereo
ALSA lib pcm_hw.c:297:(snd_pcm_hw_hw_params)
SNDRV_PCM_IOCTL_HW_PARAMS failed: Cannot allocate
memory
aplay: set_params:814: Unable to install hw params:
ACCESS:  RW_INTERLEAVED
FORMAT:  S16_LE
SUBFORMAT:  STD
SAMPLE_BITS: 16
FRAME_BITS: 32
CHANNELS: 2
RATE: 22050
PERIOD_TIME: 100000
PERIOD_SIZE: 2205
PERIOD_BYTES: 8820
PERIODS: 5
BUFFER_TIME: 500000
BUFFER_SIZE: 11025
BUFFER_BYTES: 44100
TICK_TIME: 10000

Is that patch you sent me to hack^Wfix this still
relevant, or will it make things worse? I've noticed a
few changes to these parts of the kernel drivers.

As an aside, my memory looks like this:
$ free -t
             total       used       free     shared   
buffers     cached
Mem:       1033544    1011004      22540          0   
  53776     728244
-/+ buffers/cache:     228984     804560
Swap:       498004       8168     489836
Total:     1531548    1019172     512376

Isn't Linux supposed to surrender disk-cache memory if
another process requests it? Surely *some* of that
1011004 KB cache must be usable!?
