[alsa-devel] [PATCH] alsa-utils: Spelling fixes
by David Henningsson 09 Feb '11

09 Feb '11

While looking into the Debian packaging of alsa-utils, I noticed a few patches which fix spelling errors. I'm attaching them here. If the patches attached are good for just applying, please do so or report back if there's anything I can do to get them in upstream. Thanks! -- David Henningsson, Canonical Ltd. http://launchpad.net/~diwic

[alsa-devel] [PATCH 0/2] LaCie Firewire Speakers/Griffin FireWave support
by Clemens Ladisch 08 Feb '11

08 Feb '11

This driver version is, I hope, finished enough so that I can commit it soon. The FireWave's low-frequency processing makes me believe that this device is prepared to accept two- and four-channel data, so I've enabled this in the driver; but I'd still like to actually know if it works. (If it does, adding support for the AC-3 decoding will be possible too.) I haven't yet looked into volume controls. Jay, are you OK with "Tested-by: Jay Fenlason <fenlason(a)redhat.com>"? Stefan, if those firewire core bits are worth your notice :) , please give an Acked-by for them. Regards, Clemens

With Linux kernel 2.6.37 your Webcam seems to be detected. Could you try if the volumes are up and the correct outputs are used.

[alsa-devel] ALSA: Reasonable buffer size / where should it be implemented?
by Knut Petersen 08 Feb '11

08 Feb '11

I use a RME Digi 96 PAD audio card, and I do have buffer overrun/underrun problems if I use the standard rme96c linux driver. I need a simple recording machine. It should not fail if e.g. cron starts updatedb or if I start a make -j 15 icecream compile job and decide to surf the internet while I record the digital satellite radio 48kHz stream. There is a lot of information about xrun problems, but somehow that information either does not help to prevent xruns on my system, is outdated, or asks for system changes I do not accept. No, JACK does not help. No, I do not need low latency. No, I don't want to switch to rt kernels. No, I don't want to use an audio PC without X, without cron, network, etc. The hardware provides independent 64k ringbuffers for capture and playback, that's not more than 85msec for a 96 kHz / 2 channel / 32 bit setup or ADAT. That's simply not enough for reliable operation. My private solution is a rme96.c that kmallocs 4 MB software buffers for capture and playback, data transfer between software and hardware buffer in the interrupt service routine. That does efficiently prevent xruns even on a really loaded system. But I don't know if that is the right way to go. Wouldn't it be better if there would be an (optional) software buffer one layer above the hardware driver? That would increase reliability for all audio hardware with insufficient hardware buffers. Is there any other audio hardware with similar small buffers? Has somebody already written an "extended alsa buffer" patch? Did I miss something? To put it into one question: How much buffer should be provided by an alsa hardware driver module? cu, Knut

[alsa-devel] [PATCH v8 00/12] Media controller (core and V4L2)
by Laurent Pinchart 08 Feb '11

08 Feb '11

Hi everybody, Here is the eighth version of the media controller core and V4L2 patches. Quick reminder for those who missed the previous version. let me quote the documentation (Documentation/DocBook/v4l/media-controller.xml). "Discovering a [media] device internal topology, and configuring it at runtime, is one of the goals of the media controller API. To achieve this, hardware devices are modelled as an oriented graph of building blocks called entities connected through pads." The code has been extensively reviewed by the V4L community, and this version is the first one to incorporate comments from the ALSA community (big thanks to Mark Brown and Clemens Ladisch). Two issues are not fully addressed yet, namely power management (I need to discuss this some more with the ALSA developers to really understand their requirements) and entities type names. I'm still posting this for review, as other developers have showed interest in commenting on the code. I want to emphasize once again that the media controller API does not replace the V4L, DVB or ALSA APIs. It complements them. The first user of the media controller API is the OMAP3 ISP driver. You can find it (as well as these patches and other V4L-specific patches) in a git tree at http://git.linuxtv.org/pinchartl/media.git (media-0005-omap3isp branch). The OMAP3 ISP driver patches are regularly posted for review on the linux-media list.
