[alsa-devel] $1000 bounty for getting audio working under linux on a Osprey 440
by Nathan Allen Stratton 24 Jun '07

24 Jun '07

Need to get audio working on Osprey 440 card. http://www.viewcast.com/pages.asp?page=osprey-440 The card is bt878 based, and ViewCast says it is supported on linux however not something they support. Audio is not detected by default, but does how up when you do a modprobe snd-bt87x load-all(see below). However I have not been able to pull audio from the card (only get high pitched noise). Bid may require patching bt878.c if modprobe options don't work. Only mono support is required.

[alsa-devel] pcm->private_data is NULL in alsa core!!
by Pharaoh . 22 Jun '07

22 Jun '07

Hi I am writing an alsa driver for my omap based board. I am testing it using cat /dev/audio currently, i.e. I have OSS emulation turned on. This is an initial round of testing and I will use alsa-libs and utils later. My problem is: I have set the pcm->private_data = my_chip after registering the pcm ops, after referring various standard drivers in alsa tree. My module is insmoded properly but after I do snd_card_register(card) the pcm->private_data is corrupted !! Before this step, the pcm->private_data is intact. But after looking at the snd_card_register(), I realized that it doesn't even touch the pcm pointer. So, when I cat the device I get huge segfault in snd_pcm_attach_substream(), since pcm->private_data is NULL but surprisingly all the other fields are intact in pcm pointer. Even the OSS code doesn't touch the pcm pointer, what must be wrong? I have checked my source atleast 5 times and couldn't find anything in it. -pharaoh.

[alsa-devel] AT91 SoC PCM Capture
by Paul Kavan 22 Jun '07

22 Jun '07

I am wondering what piece of code contains the capture functionality for the at91 soc. I am hoping to see how and when the pcm activates the ssc at read time. I just cannot figure out why TD0 would behave at such with this set of code and yet behave correctly with my polling code. Not a criticism....just wanting to figure this out.

[alsa-devel] Osprey 440 almost supported!!! Need X9221 i2c support!
by Nathan Allen Stratton 22 Jun '07

22 Jun '07

This card does not use analog bt878a inputs, but rather the digital input. To get audio working I set the mask to 000303, first two bits are for the audio rate, 00 is 32000, 01 is 41000, 10 is 4800. The first two bits in the next byte are for balanced or unbalanced audio input. 0x00 for unbalanced and 0x100 for balanced. So I am using: modprobe bttv card=140 bttv_gpio=1 bttv_verbose=2 bttv_debug=1 gpiomask=0x020303 audioall=0xFFFDFC bttv: Bt8xx card found (0). bttv0: Bt878 (rev 17) at 0000:08:04.0, irq: 24, latency: 132, mmio: 0xc8600000 bttv0: detected: Osprey-440 [card=140], PCI subsystem ID is 0070:ff07 bttv0: using: Osprey 440 [card=140,insmod option] bttv0: gpio config override: mask=0x20303, mux=0xfffdfc,0xfffdfc,0xfffdfc,0xfffdfc bttv0: gpio: en=00000000, out=00000000 in=00feffff [pre-init] bttv0: risc main @ 37f25000 bttv0: gpio: en=00000000, out=00000000 in=00feffff [init] bttv0: BT878A ARESET bttv0: tveeprom i2c attach [addr=0x50,client=tveeprom] bttv0: using tuner=-1 bttv0: i2c: checking for TDA9887 @ 0x86... not found bttv0: registered device video0 bttv0: registered device vbi0 bttv0: gpio: en=00020303, out=00000000 in=00fcfcfc [audio: mute] bttv0: video mux: input=0 mux=2 bttv0: gpio: en=00020303, out=00000000 in=00fcfcfc [audio: mute] bttv0: PLL: 28636363 => 35468950 .<7>bttv0: gpio: en=00020303, out=00000000 in=00fcfcfc [audio: mute] ok So the issue now is that the audio is WAY to high so it is very distorted. The audio is controlled via X9221A chips on the i2c bus at 0x50, there are not drivers for X9221 so I can't lower the audio levels. Anyone able to help me with this last part??? ><> Nathan Stratton CTO, Voila IP Communications nathan at robotics.net nathan at voilaip.com http://www.robotics.net http://www.voilaip.com

[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

[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 ***************************************

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!
