That's really good to hear. Can you close the Bug entry #2732 then? (#2799 and #2820 can be closed too, if the 9600 Hz problem is solved) So thanks a lot ...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi there It's support for the SI3054 Chip build into the Asus A8J Notebook Series. In Windows it's called "Motorola SM56". What do you mean with "sign-off"? I'm pretty happy when it walks into upstream, so that the requests on my homepage about how to patch alsa to run that modem are ceasing down. Just a small issue is left. With the alsa driver buildin into 2.6.19 slmodem is working, with any newer one (either standalone or buildin driver) we have a "hda-intel: invalid format_val, rate=9600, ch=1, format=2" error in dmesg. Seems something has been broken on that step (probably 1.0.13 to 1.0.14?). Sadly I'm not able to tell right now which alsa was included into 2.6.19. I'm trying to compare the files to get an idea what's wrong (#2799 and #2820 are reporting similar problems).

[alsa-devel] [PATCH] Add support for gain in softvol plugin
by Steve Longerbeam 18 May '07

18 May '07

Hi all, What do you think of this patch? I tested this using a stac9205 HDA codec with all sample formats supported by softvol (s32, s16, s24, big and little endian). The potential drawback I see is that softvol now has to use a intermediate long long multiply and add when computing amplified 32-bit samples. This wasn't an issue with the system I tested on, but possibly could be on slower machines. Also, are their any portability issues with using a long long datatype in alsa-lib? What is the list of embedded architectures that alsa-lib is targeted to build on? I see long long used in many other places in alsa-lib, so I'm hoping this isn't an issue. Steve

[alsa-devel] submitting a patch against the ALSA repos
by Adrian McMenamin 18 May '07

18 May '07

I have submitted my patch against the 2.6.21 kernel tree but I dare say I need to actually submit it against the alsa repos. I have a few questions: 1. Which set of sources do I patch - I assume alsa-driver - is that right? 2. How do I patch the firmware repo? As it is a binary I assume it is by some means other than patch(1) 3. This is a new architecture - there are no other SuperH drivers in alsa (afaik) - how do I add a new architecture? My memory is that when I tried this a year ago it was a bit of a nightmare.

[alsa-devel] Newbie questions regarding ALSA drivers
by Pharaoh . 17 May '07

17 May '07

Hi, I am very new to ALSA and just trying to get familier with the things, I have got few questions. 1. Is it true that all the OSS drivers are included only in directory linux/sound/oss and no where else? 2. There are arch specific folders like ARM, MIPS etc, so all the drivers in these folders are ALSA or OSS? 3. If I write a new driver for an OMAP based board, it should go in to linux/sound/arm/omap/ right? Or only ALSA drivers for this board should go there? 4. I have some old OSS drivers which were written for my board, do I need to make them ALSA drivers to be in line with the latest trend i.e. phasing out OSS drivers? -Pharaoh.

[alsa-devel] Audio driver for OMAP 730 based board - hpw to migrate from OSS to ALSA
by Pharaoh . 17 May '07

17 May '07

Hi I am new here and have slight idea about the Linux audio drivers. I am working on OMAP 730 based p2-sample board. AFAIK, there is no audio driver support for this board. I have found 2.4 drivers for the same board which I have ported to 2.6, but it is an OSS driver. So, the questions: 1. Has anyone written audio drivers for the above mentioned board? Any plans to make them open source? Any pointers will be useful regarding the same. 2. How should I go about migrating the OSS driver to ALSA, if something like this is necessary? 3. Any resources which will be helpful for writing ALSA drivers? Thanks & regards, Pharaoh.
