The driver prevents all players from proper execution

Postby elisej » Sun May 27, 2007 1:11 pm

The driver prevents all players from proper execution. Clock of all players is two time faster than the real time and system clock. The corrupted clock results in double frequences etc.
What is wrong?

You need to read man ich and there's a setting about the AD1885 rate_tuning.

Thank you very much.
I read man ich, run osstest:

Code: Select all

Sound subsystem and version: OSS 4.0 (build 1002/200704100916) (0x00040002)
Platform: SunOS/i86pc 5.10 Generic_125101-05

*** Scanning sound adapter #-1 ***
/dev/oss/ich0/pcm0 (audio engine 0): Intel ICH2 (2445)
- Performing audio playback test...
  <left> OK <right> OK <stereo> OK <measured>

*** All tests completed OK ***

Then I changed /platform/i86pc/kernel/drv/ich.conf, rebooted a system with archive update.
But nothing has changed.
I tried different intelpci_rate_tuning values, but result the same.

What do I wrong?
