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@lists.freedesktop.org ReportedBy: tvrtko.ursulin@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: [ 56.086500] HDMI hot plug event: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [ 56.086526] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [ 56.086545] ALSA sound/pci/hda/hda_eld.c:337 HDMI: ELD buf size is 0, force 128 [ 56.086561] ALSA sound/pci/hda/hda_eld.c:356 HDMI: invalid ELD data byte 0 [ 56.127063] HDMI hot plug event: Codec=0 Pin=3 Presence_Detect=0 ELD_Valid=1 [ 56.127090] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [ 56.127109] ALSA sound/pci/hda/hda_eld.c:337 HDMI: ELD buf size is 0, force 128 [ 56.127125] ALSA sound/pci/hda/hda_eld.c:356 HDMI: invalid ELD data byte 0 [ 56.387045] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [ 56.387069] ALSA sound/pci/hda/hda_eld.c:337 HDMI: ELD buf size is 0, force 128 [ 56.387086] ALSA sound/pci/hda/hda_eld.c:356 HDMI: invalid ELD data byte 0 [ 56.699469] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [ 56.699494] ALSA sound/pci/hda/hda_eld.c:337 HDMI: ELD buf size is 0, force 128 [ 56.699510] ALSA sound/pci/hda/hda_eld.c:356 HDMI: invalid ELD data byte 0 [ 56.990752] HDMI hot plug event: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [ 56.990777] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [ 56.990795] ALSA sound/pci/hda/hda_eld.c:337 HDMI: ELD buf size is 0, force 128 [ 56.990811] ALSA sound/pci/hda/hda_eld.c:356 HDMI: invalid ELD data byte 0 [ 57.001054] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [ 57.001079] ALSA sound/pci/hda/hda_eld.c:337 HDMI: ELD buf size is 0, force 128 [ 57.001095] ALSA sound/pci/hda/hda_eld.c:356 HDMI: invalid ELD data byte 0 [ 57.302064] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [ 57.302092] ALSA sound/pci/hda/hda_eld.c:337 HDMI: ELD buf size is 0, force 128 [ 57.302108] ALSA sound/pci/hda/hda_eld.c:356 HDMI: invalid ELD data byte 0 [ 57.420102] HDMI hot plug event: Codec=0 Pin=3 Presence_Detect=0 ELD_Valid=1 [ 57.420130] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [ 57.420149] ALSA sound/pci/hda/hda_eld.c:337 HDMI: ELD buf size is 0, force 128 [ 57.420165] ALSA sound/pci/hda/hda_eld.c:356 HDMI: invalid ELD data byte 0 [ 57.437447] HDMI hot plug event: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [ 57.437471] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [ 57.437489] ALSA sound/pci/hda/hda_eld.c:337 HDMI: ELD buf size is 0, force 128 [ 57.437505] ALSA sound/pci/hda/hda_eld.c:356 HDMI: invalid ELD data byte 0 [ 57.493091] HDMI hot plug event: Codec=0 Pin=3 Presence_Detect=0 ELD_Valid=1 [ 57.493117] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [ 57.493136] ALSA sound/pci/hda/hda_eld.c:337 HDMI: ELD buf size is 0, force 128 [ 57.493152] ALSA sound/pci/hda/hda_eld.c:356 HDMI: invalid ELD data byte 0 [ 57.618528] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [ 57.618552] ALSA sound/pci/hda/hda_eld.c:337 HDMI: ELD buf size is 0, force 128 [ 57.618568] ALSA sound/pci/hda/hda_eld.c:356 HDMI: invalid ELD data byte 0 [ 57.919028] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [ 57.919059] ALSA sound/pci/hda/hda_eld.c:337 HDMI: ELD buf size is 0, force 128 [ 57.919075] ALSA sound/pci/hda/hda_eld.c:356 HDMI: invalid ELD data byte 0 [ 58.220081] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [ 58.220115] ALSA sound/pci/hda/hda_eld.c:337 HDMI: ELD buf size is 0, force 128 [ 58.220131] ALSA sound/pci/hda/hda_eld.c:356 HDMI: invalid ELD data byte 0 [ 58.521039] HDMI status: Codec=0 Pin=3 Presence_Detect=1 ELD_Valid=1 [ 58.521071] ALSA sound/pci/hda/hda_eld.c:337 HDMI: ELD buf size is 0, force 128 [ 58.521087] ALSA sound/pci/hda/hda_eld.c:356 HDMI: invalid ELD data byte 0 [ 63.136948] hda-intel: IRQ timing workaround is activated for card #0.

While playing back hw_info looks fine:

Not sure what other info should I provide?
