Bug #1095242 “Sharkbay HDMI audio bug fix” : Bugs : linux package : Ubuntu

Revision history for this message

David Henningsson (diwic) wrote on 2013-01-02: [PATCH (Quantal SRU)] ALSA: hda - bug fix for invalid connection list of Haswell HDMI codec pins

#1

From: Mengdong Lin <email address hidden>

Haswell HDMI codec pins may report invalid connection list entries, which
will cause failure to play audio via HDMI or Display Port.

So this patch adds fixup for Haswell to workaround this hardware issue:
enable DP1.2 mode and override the pins' connection list entries with proper
value.

We're being advised by Intel to include the following patch for the Quantal kernel, to fix a Haswell/Sharkbay HDMI/DP audio issue. As there are no sharkbay machines out there yet, and the patch contains a "if codec->vendor_id == 80862807" I assume this will cause no regressions.

The commit is already in the 3.8 kernel, so this is just for the 3.5 SRU.

Seems to be already upstream, highly machine specific, and recommended by the manufacturer,

This bug is awaiting verification that the kernel for Quantal in -proposed solves the problem (3.5.0-22.33). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-quantal' to 'verification-done-quantal'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.
