[alsa-devel] Driver for Creamware / SonicCore Pulsar, which information needed?
by Kaspar Schleiser 22 Jun '07

22 Jun '07

Hey, I've got a Creamware Pulsar DSP card. As it actually has NO support for linux, I asked the vendor whether support was planned or if I could get necessary technical information. they answered they'd not have concrete plans on supporting linux and what information I'd need for the development of a driver. As I never wrote a driver, I don't know that, so maybe you could help me giving a useful answer ... What do we need to write a driver? Would anyone be interested in writing a driver? I could lend my card. It's a high quality multichannel card with 3 DSP chips on it. Cheers Kaspar

Hi I have to test my audio driver on an omap based board. I have got the lib and utils on my board but dont know the exact steps to follow for using aplay etc. Can anyone point me to relevant documentation? Couldn't find any. Or just brief outline about the steops to follow would be great help. -pharaoh

[alsa-devel] What is CONFIG_I2C_MODULE?
by Timur Tabi 21 Jun '07

21 Jun '07

In a lot of ALSA drivers, I see this: #if defined(CONFIG_I2C) || defined(CONFIG_I2C_MODULE) What is CONFIG_I2C_MODULE? I've searched all the Kconfigs, and I cannot see this configuration option. -- Timur Tabi Linux Kernel Developer @ Freescale

[alsa-devel] Help with SoC alsa.conf
by Paul Kavan 21 Jun '07

21 Jun '07

I am trying to determine an appropriate conf file for my AT91SAM9260ek running linux-2.6.22-rc1 and the following alsa drivers: <6>Advanced Linux Sound Architecture Driver Version 1.0.14rc4 (Wed May 09 09:51:39 2007 UTC). <6>ASoC version 0.13.0 <4>AT91SAM9260EK W6811 Driver <1> <6>w6811: W6811 PCM SoC Audio 0.1 <6>asoc: W6811 <-> at91-ssc0 mapping ok <6>grh_ek_w6811: W6811 PCM in Slave Mode <6>ALSA device list: <6> #0: GRH_EK_W6811 (W6811) I have installed alsa-lib-1.0.14a and alsa-utils-1.0.14 on the at91sam9260. The default conf file produces sound using speaker-test and aplay, but will not record using arecord. Frank Mandarino has been kind enough to lend me a barebones conf that worked for him: pcm.!default { type hw card 0 } pcm.hw { type hw card 0 device 0 subdevice 0 } ctl.!default { type hw card 0 } ctl.hw { type hw card 0 } but produces the following for me: /usr/share/alsa $ aplay -l **** List of PLAYBACK Hardware Devices **** ALSA lib conf.c:3949:(snd_config_expand) Unknown parameters 0 ALSA lib control.c:909:(snd_ctl_open_noupdate) Invalid CTL hw:0 aplay: device_list:213: control open (0): Invalid argument ALSA is *very* new to me and I am unsure how to interpret any of this. I am using a dumb W6811 pcm codec. I am fairly confident the machine/codec driver is working as expected, so I need to determine what I can do to get alsa to play nice with it as well. When I use the default alsa.conf produced from making alsa-libs, I get the following: /usr/share/alsa $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: GRHEKW6811 [GRH_EK_W6811], device 0: W6811 W6811-PCM-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 record and playing do not seem to work. When I try: /usr/share/alsa $ arecord -d5 test.wav Recording WAVE 'test.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono Aborted by signal Interrupt... It does not stop at 5 seconds....I have to interrupt it manually. Furthermore, it does not appear to record anything as when I: /usr/share/alsa $ aplay test.wav Playing WAVE ' test.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono The speaker pops once, but no audio. Finally, when I use speaker-test, I get some weird results. Doing: /usr/share/alsa $ speaker-test -r8000 -c1 -f1000 -tsine -l1 speaker-test 1.0.14 Playback device is default Stream parameters are 8000Hz, S16_LE, 1 channels Sine wave rate is 1000.0000Hz Rate set to 8000Hz (requested 8000Hz) Buffer size range from 64 to 32768 Period size range from 32 to 8192 Using max buffer size 32768 Periods = 4 was set period_size = 8192 was set buffer_size = 32768 0 - Front Left Time per period = 5.086305 Gives me a wave composed of both the 1k sine and likely a 2k sine. If I go much below 1k, I get a periodic wave, but it looks more like a heart beat. My codec expects u-law, so that may be the problem with speaker-test. However, the fact the aplay and arecord are not working give me pause. I would be greatly appreciative of any insights, pointers, etc. If there is more information that would be helpful, please ask. Thanks. Paul -- *************************************** Paul David Kavan Project Engineer GRH Electronics, Inc. 402-734-4900 pkavan(a)gmail.com ***************************************

Re: [alsa-devel] OSS/4Front

Hi Clemens, > You could compare <http://manuals.opensound.com/devlists/Linux.html> > with ALSA's sound card matrix, but the latter tends to be out of date. > Yeah, that thing is oooooold. Hopefully the new wiki on't be too bad. > > With the recent open sourcing of OSS, it would be nice to port code > > to ALSA for devices that are only currently covered by OSS. > > AFAICS all devices supported by the open-source OSS are also supported > by ALSA. > Ah, looks can be deceiving. Although both systems have 'geode' support, it seems that the OSS driver supports the CS5530 VSA2 and the SC1200. Also, there's an open bug for the Neomagic 256 driver, which may have a solution hiding away in OSS somewhere (someone with the hardware is hopefully going to help me look into that). There's a couple of things right off the bat and I don't know ALSA very well at all compared to most of you. And yeah, I know this stuff isn't in great demand, but it'd be nice if people weren't able to say that OSS can do XYZ and ALSA can't. Ash -- Get a Free E-mail Account at Mail.com!

[alsa-devel] OSS/4Front
by Ash Willis 21 Jun '07

21 Jun '07

Hi, Does anyone know if there's any kind of list showing a comparison of hardware support between ALSA and OSS/4Front? With the recent open sourcing of OSS, it would be nice to port code to ALSA for devices that are only currently covered by OSS. There has to be at least a few devices that we can grab support for, right? It may at least provide us with insight into a few bugfixes. Ash -- Get a Free E-mail Account at Mail.com!

Hi all, first post for me. I have a Yamaha DS2416 mixer card and Yamaha SW1000XG sound card that I would like to use onLinux (Fedora 6). I have used them on the "other" OS, along with ProTools, etc. Does anyone know if Linux drivers are available? I have looked around, and it seems not to be the case. any help would bve appreciated.

[alsa-devel] No time for cs4624
by chris＠idlelion.net 21 Jun '07

21 Jun '07

I really wanted to work on the cs4624 suspend resume bug (#305), but there is no time, especially given the lack of technical information. I'm wondering if I were to lend or give a laptop that exhibits the problem to one of you alsa developers, if that would be useful and provide some impetus to fix the bug, or if it would just be a big pain? Opinions? Chris
