It blew me away too.

What they were looking for was output from alsactl. Take a look at what it generates. Use the -f <filename> path to save a temporary file that can be appended to alsa-info.txt.

[alsa-devel] Salsa-lib add snd_pcm_get_params
by Matthieu CASTET 01 Feb '08

01 Feb '08

Hi, in 0.0.14, snd_pcm_get_params is missing. Is is not even in the stub form in pcm_macros.h. Why this function is missing ? As it is quite trivial, could it be added in pcm_macros.h or pcm_params.c. Thanks Matthieu

[alsa-devel] [PATCH/KCONFIG] - Add SUPERH depends to sound/soc/sh/Kconfig
by Kristoffer Ericson 01 Feb '08

01 Feb '08

Currently you will see an empty "SoC Audio support for SuperH" menu when building for other archs (example pxa). This patch adds "depends on SUPERH" to remove that empty menu. signed-off-by: Kristoffer Ericson <kristoffer.ericson(a)gmail.com> diff --git a/sound/soc/sh/Kconfig b/sound/soc/sh/Kconfig index f03220d..4c1e013 100644 --- a/sound/soc/sh/Kconfig +++ b/sound/soc/sh/Kconfig @@ -1,4 +1,5 @@ menu "SoC Audio support for SuperH" + depends on SUPERH config SND_SOC_PCM_SH7760 tristate "SoC Audio support for Renesas SH7760"

[alsa-devel] es1938 - patch trying to improve capture hw pointer reads
by Hermann Lauer 01 Feb '08

01 Feb '08

Hello, with the Solo1 (es1938) I got a lot of xrun's during capture on my machine. Tracing that down it seems to be comming from reading ocassionaly bad hw pointers from the chip. Appended is a patch against linux-2.6.23.12 which uses more checking to avoid that false pointer reads. Failed reads are giving back the last good value read instead of spinning in a tight loop, which seems more appropriate to me in an interrupt. I think I saw this trick used in another driver. On my machine xruns seems to be gone with that patch. If anybody is interested, mmaped capture seems also to be doable with some tricks, still testing this...

[alsa-devel] Roland UA-30 works
by Victor Roetman 01 Feb '08

01 Feb '08

I just tested a Roland UA-30 USB sound card, and it seems to work fine. I wanted to add it to the sound card matrix on http://www.alsa-project.org/main/index.php/Matrix:Vendor-Roland_Edirol but when I click edit, it says "This page has been locked to prevent editing." Can someone add this for me? Or tell me how to add it? On Ubuntu 7.10 it seems to work fine with playback and with recording, and when the 44.1/48 kHz switch is changed, the device seems to be removed and added again with the correct frequency shown in /proc/asound/cards.

Usually arecord is the best as a primary test. Simply run % arecord -fdat -vv somefile.wav To avoid any possible bugs in alsa-lib, also try % arecord -Dplughw:0 -fdat -vv somefile.wav > > The patch below enables AK4114, and possibly fixes some ADC setup. > > Give it a try. > Cool! we will try it this evening and give a feedback.

[alsa-devel] M-Delta Audiophile 192 (ice1724) Recording
by CAG 31 Jan '08

31 Jan '08

Hi, we use the M-Delta Audiophile 192 with alsa-driver-1.0.15 and the ice1724 module. Playback works but we cannot record anything. I noticed that this maybe a bug according to the Alsa Changelog: From Changes v1.0.13 v1.0.14: > > - ice1724 - Add support of M-Audio Audiophile 192 > > Added the (experimental) support of M-Audio Audiophile 192 board. > Currently, the analog and the digital playbacks seem working fine. > The inputs seem not working as far as I've tested yet. How is the status for that card ? Is someone working on this ? I heard Recording with OSS works but actually we don't want to switch to OSS... Is it worth waiting for a new release ? We desperately need recording! Cheers from a free radio station, Toast
