             Bug #: 46713
           Summary: HDMI audio played back at a wrong rate
    Classification: Unclassified
           Product: DRI
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: tvrtko.ursulin at onelan.co.uk


I am experiencing audio being played back at roughly 28665Hz instead of
expected 44100Hz. This rate is derived for timing for how long it takes to play
sample of a known size. Pitch of audio being played is obviously comical.

Hardware:
AMD G-T56N (Radeon HD 6310) box connected to the monitor via native HDMI
connector.

This is with kernel.org 3.3.0-rc4 kernel.

Only thing I see in kernel log with apparent relevance is this:

Suggest a bigger bdl_pos_adj.

While playing back hw_info looks fine:

aplay -l

Not sure what other info should I provide?
