[alsa-devel] [PATCH 1/2] ASoC: Implement new DC servo readback mode for late WM8994 revisions
by Mark Brown 01 Aug '11

Later WM8994 devices implement a new DC servo readback mode with the register used to access the offset moved to register 0x59. Implement support for this and enable it on the appropriate devices.

[alsa-devel] Some more on MSI GX740 and HDA Intel (bug 5321)
by K900 01 Aug '11

01 Aug '11

Sorry for disappearing last time, I've been quite busy at the time. But I managed to find a bit more on my laptop's sound card and how to make it work. I've found two nodes that actually produce (some) sound when connected to a mixer. 0x1b pin complex is connected to front speakers and 0x16 to the center/LFE thingy. However, I can only get sound from them when I connect them to 0x0c and 0x0e mixers, that both (why?) output the sound from front channels. So, there's no mixer that outputs rear or LFE channels. To be honest, I don't understand anything further than this, so can someone please help me :) I'll try to be around on IRC most of the time. Also, my JID is k900(a)neko.im. // Note: it seems my last mail was lost somewhere. Correct me if I'm wrong.

Re: [alsa-devel] Copy ALSA buffer to the buffer allocated in my driver.

These fields are controlled by your driver, although typically they are set by ALSA helper functions. substream->dma_buffer is the preallocated buffer; if your driver doesn't do preallocation, it is not set. The actual buffer, if it exists and is accessible by the CPU from kernel space, is in substream->runtime->dma_area. Regards, Clemens
