[alsa-devel] [PATCH] hda-intel: support for iMac 24'' released on 09/2006
by Nicola Fagnani 23 Jul '07

23 Jul '07

Basic audio support for the iMac 24'' model released on 09/2006, including headphone jack detection with automatic speaker muting. This iMac uses the Realtek ALC885 codec, not a Sigmatel one as in other models. Functionality has been tested for internal speakers, headphone and microphone.

[alsa-devel] ALSA-USB driver issues with C-Media chipset
by Saurav SAHU 20 Jul '07

20 Jul '07

We have encountered some audio recording quality issues on the recent ALSA-USB drivers. These problems are faced on C-Media chipset based external USB audio devices. The recorded audio with 'arecord' is quite noisy, unclear and jerky. The version of ALSA I encountered are 1.0.12 and beyond. It seemed to work well previously on ALSA version 1.0.8. If I record with a Philips webcam mic (Philips chipset), the audio recording is very clear on across all ALSA versions. In case you have observed similar issues with C-Media drivers and aware of them, please let me know. Best Regards Saurav

[alsa-devel] Noise Problem with rate convert plugins
by Andreas Rumpler 20 Jul '07

20 Jul '07

Hello, I'm new to this list.I hope someone could help me with a problem concerning the samplerate converter plugins of the alsa driver. Firstly some facts about my application. - Envy24 (VT1270) pci audio chip on a custom mainboard - playback of sounds/music with different sample rates from 8kHz to 48kHz (sample rate of the files) - the hardware (Envy24 chip) must always run with 44.1kHz or 48kHz (selectable by user), because the audio is outputed by a DAC and SPDIF and the SPDIF clock must not be changed according to the sample rate of the files. - Kernel is 2.6.22 and alsa is 1.0.14 So I'm using the samplerate (libsample rate based) plugin from the alsa-plugin package. Generaly it works very good. My problem is: Every time a playback is started a short plop noise is heard. The noise is on analog and SPDIF output. If I don't use the samplerate converter the noise is not heard at all. So it comes definitely from the rate converter plugin, I think. Changing the quality level of the plugin don't solve the problem. I've also switched to the new Speex rate converter plugin. With this plugin there is no noise at the start of playback. But here I have trouble with awful noise at some rate conversions (6kHz(source) -> 48kHz(output); 11.025kHz -> 44.1kHz; 22.05kHz -> 44.1kHz). So it's even worse than using the libsamplerate plugin. Finaly I've tried the libavcodec plugin, which is the worst according to noise. Could any comment this problem, please? This is my asound.conf: ############################################## # Playback over Line-Out and SPDIF simultaniously as default pcm.!default { type plug slave.pcm { type multi slaves.a.pcm "plughw:0,0" slaves.a.channels 2 slaves.b.pcm "hw:0,1" slaves.b.channels 2 bindings.0.slave a bindings.0.channel 0 bindings.1.slave a bindings.1.channel 1 bindings.2.slave b bindings.2.channel 0 bindings.3.slave b bindings.3.channel 1 } ttable.0.0 1 ttable.1.1 1 ttable.0.2 1 ttable.1.3 1 } pcm_slave.s1 { pcm default rate 44100 } pcm_slave.s2 { pcm default rate 48000 } pcm.rate_convert_44100 { type rate slave s1 converter samplerate } pcm.rate_convert_48000 { type rate slave s2 converter samplerate } ##################################################### Regards Andreas Rumpler

[alsa-devel] The users view of an audio card
by David Webb 20 Jul '07

20 Jul '07

I've been editing a couple of the unofficial wiki pages and a number of issues have arisen. My own system has the NVidia/Realtek motherboard chips so I may be in the dark about what is available on other chips. Some of the questions are background to ensure that what I write later in the wiki is correct. Takashi Iwai suggested I raise the issues here: 1. A large number of users seem to be reporting problems with Nvidia and Via soundcards. As far as I can tell Nvidia and Via do not produce soundcards but they do produce chipsets with southbridges which can connect to a motherboard audio chip. The when alsamixer (or Kmix) runs it reports something like: Card: NVidia CK804 Chip: Realtek AL650 rev 0 Presumably because the southbridge is the primary PCI device. So: 1.1 Is the above always correct (so I can add it to the wiki)? 1.2 Could alsamixer etc be modified to give a more sensible answer for non-experts. Something like: Card: Motherboard via NVidia CK804 Chip: Realtek AL650 rev 0 might work. I presume a look-up table is used to convert the PCI 2-byte integers to the above names so presumably the extra information needed could be obtained at this level. 2. On different motherboards a Realtek 650 may be connected using a NVidia CK804 with the intel8x0 alsa driver or using a VIA VT8233 with the vt82xx driver. 2.1 Given that the audio chip registers are the same in both cases why are two different drivers needed? (Are they?) 2.2 If it is something to do with the southbridges, where may the manuals that describe the differences be found? 2.3 What would happen if the motherboard manufacturers kept the same southbridges but started using an audio chip with a different set of registers? (2.2a Where can an AD'97 manual be found? - I could not find one on the intel site) 3. The Realtek 650 datasheet implies that independently of the mixing in the main input -> line-out pathway, the input to the ADC (i.e. on capture) may include more than one source (i.e. both audio and microphone). However alsamixer (and kmix) only allows me one input stream. So: 3.1 Is the manual misleading or have I misread it? 3.2 Is the manual correct but the driver is based on an earlier intel chip which did not have this facility? Related to this the manual seems to show a number of options which I cannot identify in alsamixer. For example the manual shows two surroundsound volume stages between which there are switched links, one to and two from the main stero path. Alsamixer shows a single amplifier. It has one link 'from' the main path but I could not find a link 'to' the main path. 3.3 Is the driver assuming a old layout which fits most of the new audio chip layout but not all? (This is really a question about what sort of warnings/advice should my write up include). 3.4 At which stage does alsa relate the registers to the descriptions, aux-volume, aux-mute etc? Again does it assume a layout which fits most aspects of the chips listed? Thats enough for the moment. I presume I could sit down for a year and read and understand the code - but in the meantime any help will be welcome. Regards, David Webb.

[alsa-devel] Problem and workaround for Intel HDA
by Yann Le Brech 20 Jul '07

20 Jul '07

The problem : missing controls of the sound cards for an Intel HDA, Toshiba Satellite Pro U200 Full description : I was using the kernel 2.6.19 for a while, and I got some interesting functions like controlling the sound level on headphones or speakers separately. Then I upgraded to the kernel 2.6.21.1 and suddently the level controls changed, to useless level controls, like Master and PCM only (and some other useless). I wanted to get back to the previous control set, and I've found a solution by checking what was done in debugging mode. The previous kernel was not detecting the model config, but the new one did. So I simply strapped the detection routine by a return -1 and it did the trick. I know its not the best thing to do, but it was the simplest thing I thought about. Outputs : 2.6.19's Alsa output : ALSA sound/pci/hda/hda_intel.c:695: codec_mask = 0x3 2.6.21.1 : ALSA sound/pci/hda/hda_intel.c:695: codec_mask = 0x3 ALSA sound/pci/hda/hda_codec.c:1757: hda_codec: model 'toshiba' is selected for config 1179:1 (Toshiba U205) How to see the problem : Just see the list of controls in any mixer software. Environment : Toshiba Satellite Pro U200 Software : KateOS 3.2 with Linux 2.6.19 (working) and 2.6.21.1 (not working) Workaround : int __devinit snd_hda_check_board_config(struct hda_codec *codec, int num_configs, const char **models, const struct snd_pci_quirk *tbl) { return -1; // WORKAROUND if (codec->bus->modelname && models) { int i; for (i = 0; i < num_configs; i++) { if (models[i] && -- a++ Y.
