[alsa-devel] [PATCH] echoaudio, about changeset 5389
by Giuliano Pochini 17 Sep '07

17 Sep '07

About changeset 5389: Remove superfluous volatile prefix. It's fine, except for the struct comm_page.handshake which is polled by echoaudio_dsp.c::wait_handshake(). Without volatile we need another way to prevent the compiler from moving the read outside of the loop. If I overlooked something, please let me know. Short descr.: This patch adds a barrier() to prevent the compiler from moving the read outside of the loop. It also fixes a comment.

[alsa-devel] simple ALSA source code?
by william estrada 16 Sep '07

16 Sep '07

Hi guys, I am looking for a 'simple' C player program that uses ALSA. I found this link "http://www.linuxjournal.com/article/6735/print" which has sample code but it is old and does not work. The player produces noise from a file created with arecord. I am looking for a set of simple programs for creating and playing wav files. Something I could modify for my needs. I want command line interface type not a GUI. Thanks for your time. -- William Estrada MrUmunhum(a)popdial.com Mt-Umunhum-Wireless.net ( http://Mt-Umunhum-Wireless.net ) Ymessenger: MrUmunhum

[alsa-devel] Per option CFLAGS?
by Rene Herman 15 Sep '07

15 Sep '07

Hi Kai, Sam. I have a single file foo.c that I want to generate two (ALSA) modules from, snd-foo2000.ko and snd-foo2001.ko, by compiling with either FOO2000 or FOO2001 defined. I can do this, and ALSA does this a few times, by providing dummy foo2000.c and foo2001.c files, like: === foo2000.c #define FOO2000 #include "foo.c" === and a regular Makefile === foo2000-objs := foo2000.o foo2001-objs := foo2001.o obj-$(CONFIG_SND_FOO2000) += snd-foo2000.o obj-$(CONFIG_SND_F002001) += snd-foo2001.o === That #include is a little lame though. Is there a nicer way? I noticed the per-file CFLAGS, but given that it's one source file for both, that doesn't fit. Rene.

[alsa-devel] Sony VAIO FZ19VN (snd_hda_intel)
by Pablo Yaggi 15 Sep '07

15 Sep '07

Hi, i bought a sony vaio fz19vn, i try both modes for the snd_hda_intel, vaio and vaio-ar, the same problem happen with them, when i plugin the headset internal speakers are not muted, so here is the card info. I read the changelog for version 1.0.15 and it says automute was added for the AD1986 which has jack detection, but this is a different codec. I have programming skills but i'm not familiarized with alsa internals, so ask me anything you need and i try to help. It would be nice a control to enable/disable automute and another two to enable/disable internal and external speakers.

[alsa-devel] Ensoniq SoundScape VIVO90
by Krzysztof Helt 14 Sep '07

14 Sep '07

Hi, I acquired Ensoniq VIVO90 card. I tried sscape driver but it does not work. I quickly looked at the oss driver in the kernel and it works completely different (uses different pnp resources for codec and mpu). I want to ask if somebody tested this driver and if so what was the Ensoniq card model. If it worked only for non-pnp models I would integrate at least for VIVO cards. BTW. I found the old post which describes difference between VIVO and VIVO90. It is below the email. Regards, Krzysztof Hannu Savolainen (ha...(a)voxware.pp.fi, ha...(a)4front-tech.com) wrote: Temat: Re: Ensoniq VIVO vs. VIVO 90 Bill Plenderleith <nospam!plend...(a)nortel.ca> writes: >Are VIVO & VIVO 90 different products? >Can anyone summarize the diffences? The only difference is that in VIVO90 the wave table output signal goes through the codec/mixer chip (AD1845). In the original VIVO it's summed to the output of AD1845. This difference is'n really anything important. Best regards, Hannu

[alsa-devel] SALSA: snd_pcm_avail_update
by J. Scott Merritt 14 Sep '07

14 Sep '07

Using salsa-lib-0.0.11, cross-compiling to ARM ... Despite my best efforts, snd_pcm_avail_update is always returning "broken pipe". I have checked the pcm_state of the Capture Handle just before snd_pcm_avail_update and it is "RUNNING'. But immediately after snd_pcm_avail_update it always returns "XRUN". Furthermore, this same sequence seems to work properly with the standard ALSA-Lib. Test program is attached. Any suggestions appreciated. Thanks, Scott.

[alsa-devel] How do I update the ALSA SoundCard Matrix?
by Timur Tabi 14 Sep '07

14 Sep '07

I'm looking at http://bugtrack.alsa-project.org/main/index.php/Matrix:Main. I'm trying to add information on the CS4270 driver that I wrote, but I just don't get it. I know how to edit normal Wiki pages, but this looks different. It looks like all the information is obtained from some database somewhere. This page http://bugtrack.alsa-project.org/main/index.php/Help:Howto-Edit supposedly tells me how to edit, but it's useless. It doesn't really tell me *how* to edit, it just tells me that it can. So what am I missing? How do I add information on a new driver? I'll need to add information on a new vendor soon, too. -- Timur Tabi Linux Kernel Developer @ Freescale

[alsa-devel] ALSA changes in 2.6.23-rc6 for Intel HDA
by Jon Smirl 13 Sep '07

13 Sep '07

The ALSA changes in 2.6.23-rc6 for Intel HDA made me change my volume from about 30% to 75% to get the same level of sound. Was this intentional? My ALSA info is here. http://pastebin.ca/692226 -- Jon Smirl jonsmirl(a)gmail.com
