[alsa-devel] I don't understand snd_pcm_ops
by Timur Tabi 19 May '07

19 May '07

I'm new to ALSA driver development, and I'm writing an SOC driver for new hardware. Can someone explain to me what the snd_pcm_ops structure is for? And it sounds like a stupid question, but after studying documentation and sample code, I'm still confused. First off, I thought PCM stood for Pulse Code Modulation, but that just describes the format of the digital data. I don't understand what a PCM operation could be. I've seen documentation where PCM is considered an alternative to I2S or AC97. But if you look at eti_b1_wm8731.c, you'll see this: #include "at91-pcm.h" #include "at91-i2s.h" So is the AT91 a PCM device or an I2S device??? Some background: I'm writing driver for a new SOC that has an I2S interface, and it's talking to a CS4270 codec, but the CS4270 codec is wired up in "stand-alone" mode, so there's no software configuration. -- Timur Tabi Linux Kernel Developer @ Freescale

Re: [alsa-devel] Alsa 1.0.13 (and others) does not work on ALC880

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear Tobin thank you for your so helpful recommendations ! In fact the key was probe_mask=1. But I did not see this option in the hda-intel module description :-( ... Now I added probe_mask)=1 in /etc/modprobe.d/alsa-base and it works either with 1.0.13 or 14rc4 :-). In fact when alsa is compiled with debug=detect this option is not necessary any more and sound works even without this option ... Does this option (probe_mask=1) limitates something in the sound system ? Is it better to not use it or is it painless for audio possibilities ? Thank you again for your help !!! Now to be more precise : 1) If I compile 14rc4 with debug=detect it can be compiled, modules can be inserted : - --> when inserted with # modprobe -v snd-hda-intel model=clevo I get in /var/log/messages : May 18 22:32:05 gondor kernel: [ 6012.711362] ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 17 (level, low) -> IRQ 20 May 18 22:32:05 gondor kernel: [ 6012.774627] ALSA /usr/src/modules/alsa-driver-1.0.14rc4/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:698: codec_mask = 0x3 May 18 22:32:06 gondor kernel: [ 6013.404197] ALSA /usr/src/modules/alsa-driver-1.0.14rc4/pci/hda/hda_codec.c:1795: hda_codec: model 'clevo' is selected May 18 22:32:08 gondor kernel: [ 6015.083303] ALSA /usr/src/modules/alsa-driver-1.0.14rc4/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:558: hda_intel: azx_get_response timeout, switching to polling mode... - -> when inserted with # modprobe -v snd-hda-intel model=clevo probe_mask=1 I get in /var/log/messages : May 18 22:32:50 gondor kernel: [ 6057.162063] ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 17 (level, low) -> IRQ 20 May 18 22:32:50 gondor kernel: [ 6057.243574] ALSA /usr/src/modules/alsa-driver-1.0.14rc4/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:698: codec_mask = 0x3 May 18 22:32:50 gondor kernel: [ 6057.873098] ALSA /usr/src/modules/alsa-driver-1.0.14rc4/pci/hda/hda_codec.c:1795: hda_codec: model 'clevo' is selected 2) If I compile 14rc4 with debug=none it can be compiled, modules can be inserted : - --> when inserted with # modprobe -v snd-hda-intel model=clevo I get in /var/log/messages : May 18 19:39:46 gondor kernel: [ 2366.086099] ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 17 (level, low) -> IRQ 20 May 18 19:39:49 gondor kernel: [ 2368.491630] ALSA /usr/src/modules/alsa-driver-1.0.14rc4/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:558: hda_intel: azx_get_response timeout, switching to polling mode... and aplay gives : eric@gondor:/usr/src/modules/alsa-driver-1.0.14rc4$ aplay ALSA lib pcm_direct.c:867:(snd_pcm_direct_initialize_slave) snd_pcm_hw_params_any failed ALSA lib pcm_dmix.c:876:(snd_pcm_dmix_open) unable to initialize slave aplay: main:550: Erreur d'ouverture audio: Argument invalide eric@gondor:/usr/src/modules/alsa-driver-1.0.14rc4$ - --> when inserted with # modprobe -v snd-hda-intel model=clevo probe_mask=1 May 18 19:41:45 gondor kernel: [ 2484.283312] ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 17 (level, low) -> IRQ 20 And it works !!!!

[alsa-devel] Linux 2.6.21 regression with hda-intel (Conexant 5045)
by Gunter Ohrner 18 May '07

18 May '07

Hi! First of all: Sorry if this question is dumb or a fix should be obvious, but as a non-ALSA_expert I'm a bit a a loss at the moment... I searched the bugtracker and this list but could not find anything appropriate - most probably I missed a relevant post or didn't recognize it as being relevant... Any pointers are greatly appreciated! The situation is as follows: Using Linux 2.6.20.4, my laptop's soundcard works just fine. Using 2.6.21.1, it also works, but the headphone socket is dead. Plugging a headphone into it correctly mustes the internal speakers, but no sound is output via the headphones. Details: - Fujitsu Simens Amilo Si1520 - Codec: Conexant ID 5045 (as reported by Linux 2.6.20.4) Alsa device details between both Linux kernels differ completely, with Linux 2.6.20.4 only reporting a single a single analog PCM device and Linux 2.6.21.1 reporting a Conexant Analog and a Conexant Digital device. Should I still post the complete information from /proc/asound/* for both kernels? I tried applying conexant-test22.patch by Tobin Davis, but it does not seem to match the in-kernel ALSA code. It also does not seem to be related to the 5045 chip... Any ideas? Greetings, Gunter

-----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.
