[alsa-devel] [PATCH 00/11] Intel IbexPeak HDMI codec support
by Wu Fengguang 30 Oct '09

30 Oct '09

Hi Takashi, This series adds support for the Intel IbexPeak HDMI codec, which can connect up to 3 monitors and support 2 independant A/V pipes. The patches are tested OK on IbexPeak and G45. DisplayPort is also working with another in-house KMS patch. However we have not tested dual monitor configurations (which should be rare for now). Thanks, Fengguang

[alsa-devel] [PATCH] ASoC: sh: FSI: Remove DMA support
by Kuninori Morimoto 30 Oct '09

30 Oct '09

SuperH FSI device have the hardware limitation to use DMA. If DMA is used, LCD output will be broken. Maybe there are some solution. But I don't know how to do it now. This patch remove DMA support and use soft transfer.

Hm, I don't see any affecting changes between 2.6.30 and 31. Just as a test, could you copy sound/usb/*.[ch] from 2.6.30 tree to 2.6.31 or 32-rc and check whether the same problem appears? Takashi
