[alsa-devel] Need help with alsa dev wiki migration
by Eliot Blennerhassett 10 Aug '07

10 Aug '07

Greetings, Anybody who can figure out where to put the pages in the ToDo section of this page please step forward now... http://bugtrack.alsa-project.org/main/index.php/DriversInDevelopment The remaining pages in todo here are users home pages, would be great if those users would migrate them. http://bugtrack.alsa-project.org/main/index.php/Developer_Zone Other than these, the contents of the alsa developers wiki has been copied to the alsa wiki. Other eyes checking that this has been done satisfactorily would be appreciated thanks Eliot

[alsa-devel] pcm_empty.c in doxygen
by Rolland Dudemaine 10 Aug '07

10 Aug '07

Hi, It looks like the doxygen-generated documentation lacks the pcm/pcm_empty.c bit. Since the default plugin uses empty as plugin, it's useful to have docs for it. Here is a diff to apply to solve this. --- doc/doxygen.cfg.old 2007-08-10 13:14:00.000000000 +0200 +++ doc/doxygen.cfg 2007-08-10 13:14:38.000000000 +0200 @@ -72,6 +72,7 @@ ../src/pcm/pcm_ioplug.c \ ../src/pcm/pcm_misc.c \ ../src/pcm/pcm_simple.c \ + ../src/pcm/pcm_empty.c \ ../src/rawmidi \ ../src/timer \ ../src/hwdep \ Best Regards, --Rolland Dudemaine

[alsa-devel] Bug 305
by chris＠idlelion.net 10 Aug '07

10 Aug '07

I tested Fedora 8 on my ThinkPad 600X. The 600X has a CS4264, and F8 uses a 2.6.23 kernel (I forget the version at the moment). The sound does not work after resume. How should I check whether the fix for this issue is included in a kernel? Version number? Thanks, Chris

[alsa-devel] Audigy: recording level much too low (microphone)
by Zbigniew Baniewski 10 Aug '07

10 Aug '07

Hallo, I've got a problem with Audigy (it's SB0230 release) soundcard: the recording level, when taking the sound from microphone, is much too low. I've sent a mail to "users" list, so here I'm just pointing to that mail: http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg20235.html ...and so I won't repeat it all here. (I made a mistake in the subject there, writing about "Audigy2") My card is seen by 1.0.14 ALSA as ( cat /proc/asound/cards ): 0 [Audigy ]: Audigy - Audigy 1 [Unknown] Audigy 1 [Unknown] (rev.3, serial:0x5a1102) at 0xc400, irq 11 As I understand, there is some variable (or register?), which controls that recording level for microphone input - perhaps someone of the developers could tell me, which variable is it, and which file should I search? In such way perhaps I could fix it on my own - just by setting higher max. level, or in similar way. But searching all that files on my own could take serious amount of time, I'm afraid. Or perhaps there's another way to fix it (some special settings)? -- pozdrawiam / regards Zbigniew Baniewski

[alsa-devel] [PATCH] ad1848-lib Makefile cleanup

[alsa-devel] C-Media 8788
by Pekka.Panula＠sofor.fi 10 Aug '07

10 Aug '07

Hi Any inside info about C-Media 8788 support, i see that repository contains some sort of driver for it, but what state is it, is it working as wiki says its about 35% done. Happy to know also if its going for Linux 2.6.23 kernel? I think lot of people would be happy to get it to kernel soon as possible as it seems Creative has serious delays about x-fi driver (i wonder if there will be any Linux support at all, not looking good) and many people are thinking about Razer barracuda AC-1 or Auzentech X-Meridean which uses C-Media 8788 chipset.

[alsa-devel] Why there is no SNDRV_PCM_RATE_24000 in pcm.h
by Wei Kai 10 Aug '07

10 Aug '07

hi, guys I checked the include/sound/pcm.h in kernel and find this problem, it seemed strange, so many codecs support the 24000 sample rate, why there is no such definition. Any special concern?

[alsa-devel] [PATCH] Add quirk for Stanton ScratchAmp v1
by Mark Hills 10 Aug '07

Hello, This patch is a USB quirk to ensure the Stanton Scratchamp v1 is detected (bugtrack #2932). The interface is two USB devices in the same physical box.
