[alsa-devel] [PATCHv2] ASoC: core: Don't set "(null)" as a driver name
by Jarkko Nikula 21 May '11

21 May '11

Commit 22de71b ("ASoC: core - allow ASoC more flexible machine name") writes "(null)" to driver name string in struct snd_card if card->driver_name is NULL. This causes segmentation faults with some user space ALSA utilities like aplay and arecord. Fix this by using the card->name if no driver name is specified.

[alsa-devel] Should we really use POS_FIX_VIACOMBO for AMD/ATI chipsets?
by David Henningsson 20 May '11

20 May '11

I'm far from sure, but I could be on to something... Looking at the code for azx_via_get_position, it seems that for recording streams, it accesses a register at position VIA_IN_STREAM0_FIFO_SIZE_OFFSET = 0x90. Looking at the datasheet for SB700, that register is not even present. This does not seem right to me. Could it be that we should use POS_FIX_LPIB by default for AMD/ATI chipsets instead? It seems more reasonable to me. In addition, I looked through some of the commits for quirking to POS_FIX_LPIB and the four I checked were all ATI chipsets. So; I've tried adding: options snd-hda-intel position_fix=1 to /etc/modprobe.d/alsa-base.conf ...to my machine with the infamous [1002:4383] controller (and rebooted), and the few times I've tested, recording worked successfully with pulseaudio. So could you please follow this up with testing on your machines to see if we have actually managed to solve this long-standing bug? The only annoying thing is that I didn't realise this earlier :-/ -- David Henningsson, Canonical Ltd. http://launchpad.net/~diwic

[alsa-devel] [HEADSUP] Please submit something for the Audio track at LPC!
by Lennart Poettering 20 May '11

20 May '11

Heya, The Linux Plumbers Conference 2011 is coming soon. Mark Brown and I are running the Audio track at LPC, and we are looking for more proposals! So, please consider submitting something if you haven't done so yet. We are looking for all kinds of technical talks covering everything audio plumbing related: audio drivers, audio APIs, sound servers, pro audio, consumer audio. If you can propose something audio related -- like talks on media controller routing, on audio for ASOC/Embedded, submit something! If you care for low-latency audio, submit something. If you care about the Linux audio stack in general, submit something. LPC is probably the most relevant technical conference on the general Linux platform, so be sure that if you want your project, your work, your ideas to be heard then this is the right forum for everything related to the Linux stack. And the Audio track covers everything in our Audio Stack, regardless whether it is pro or consumer audio. So, submit! submit! submit! (And contrary to what the web site might suggest regarding deadlines we'll still consider your submission, if you post it quickly!) http://www.linuxplumbersconf.org/2011/ Lennart -- Lennart Poettering - Red Hat, Inc.

[alsa-devel] [PATCH 1/2 v3] ASoC: soc-cache: Block based rbtree compression
by Dimitris Papastamos 20 May '11

20 May '11

This patch prepares the ground for the actual rbtree optimization patch which will save a pointer to the last accessed rbnode that was used in either the read() or write() functions. Each rbnode manages a variable length block of registers. There can be no two nodes with overlapping blocks. Each block has a base register and a currently top register, all the other registers, if any, lie in between these two and in ascending order. The reasoning behind the construction of this rbtree is simple. In the snd_soc_rbtree_cache_init() function, we iterate over the register defaults provided by the driver. For each register value that is non-zero we insert it in the rbtree. In order to determine in which rbnode we need to add the register, we first look if there is another register already added that is adjacent to the one we are about to add. If that is the case we append it in that rbnode block, otherwise we create a new rbnode with a single register in its block and add it to the tree. In the next patch, where a cached rbnode is used by both the write() and the read() functions, we also check if the register we are about to add is in the cached rbnode (the least recently accessed one) and if so we append it in that rbnode block.
