[Alsa-user] how do I change sample rate ?

[Sergei S. <ste...@li...>]

Hello All,

on the one hand, I see this:

"
sergei@z61m:~> grep -r 48000 /proc/asound
/proc/asound/Intel/codec#0:    rates [0x7f]: 8000 11025 16000 22050 32000 44100 48000
/proc/asound/Intel/codec#0:    rates [0x60]: 44100 48000
/proc/asound/Intel/codec#0:    rates [0x7f]: 8000 11025 16000 22050 32000 44100 48000
/proc/asound/card0/codec#0:    rates [0x7f]: 8000 11025 16000 22050 32000 44100 48000

- I think this means my card is capable of supporting

8000 11025 16000 22050 32000 44100 48000

sample rates.

On the other hand, I see this:

"

- I think this means there are no sample rate switches.

How do I change sample rate ?

The card is AD1981, ALSA version is

Advanced Linux Sound Architecture Driver Version 1.0.14 (Thu May 31 09:03:25 2007 UTC).

- it's SUSE 10.3 on z61m laptop.


Thanks,
  Sergei.
