[alsa-devel] possible regression in creative x-fi expresscard
by Susan Cragin 15 Nov '09

15 Nov '09

Recently my Creative X-fi expresscard has stopped working properly. It may be an alsa problem but it may also be some sort of bus problem, and I thought I'd let you decide. I filed Ubuntu bug 462843, which describes it in detail, but basically here's what happens. Sound usually works when I start the computer. But when I close and re-open my application, sound has gone. At the same time, alsamixer shows the card properly. The settings are fine. Asoundconf shows that the card is still there and registered as the default. sudo modprobe snd-hda-codec sudo modprobe snd-hda-codec-ca0110 shows that either the modules are loaded correctly or are able to be re-loaded, but still no sound. I fix by removing and re-inserting the card, and then re-booting the computer. This is for incoming (recorded) sound. I haven't checked the outgoing sound. I have the current Ubuntu version of the drivers, and have not tinkered with them at all. I re-installed the whole system recently. I updated to Lucid hoping to get better updates but that did not help. Here's everything interesting from dmesg|tail. [ 4.088837] sdhci-pci 0000:09:01.1: SDHCI controller found [1180:0822] (rev 22) [ 4.088853] sdhci-pci 0000:09:01.1: PCI INT B -> GSI 17 (level, low) -> IRQ 17 [ 4.099720] mmc0: SDHCI controller on PCI [0000:09:01.1] using PIO [ 4.233046] HDA Intel 0000:00:1b.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22 [ 4.235589] HDA Intel 0000:00:1b.0: setting latency timer to 64 [ 4.352945] HDA Intel 0000:05:00.0: PCI INT A -> GSI 18 (level, low) -> IRQ 18 [ 4.500172] hda-intel: spurious response 0x0:0x0, last cmd=0x000000 [ 5.503012] hda-intel: azx_get_response timeout, switching to polling mode: last cmd=0x101f0012 [ 6.505012] hda_intel: azx_get_response timeout, switching to single_cmd mode: last cmd=0x101f0012

[alsa-devel] handling of underrunning snd_pcm_writei
by Mads Kiilerich 14 Nov '09

14 Nov '09

Hi, I AM trying to convert an internal app from oss to alsa and is trying to grok the alsa API and the examples I can find. I would like to ask some questions to avoid guessing and making wrong assumptions. Feel free to redirect me to where I should have found the answer myself. http://www.alsa-project.org/alsa-doc/alsa-lib/group___p_c_m.html#gf13067c0e… says about snd_pcm_writei: > Returns: a positive number of frames actually written otherwise a negative error code > ... > Return values: > ... > -EPIPE an underrun occurred > ... > The count of bytes can be less only if a signal or underrun occurred. So what is returned in case of underrun? Error code or count of bytes? Should snd_pcm_recover always be used to get the byte count after -EPIPE? snd_pcm_recover is neither mentioned in the link above nor in http://www.alsa-project.org/alsa-doc/alsa-lib/pcm.html , so I don't feel confident about that. And is it measured in "positive number of frames actually written" or "count of bytes"? It surprises me that snd_pcm_writei shows non-blocking behaviour in case of underruns and don't use all the offered data. I would guess that it either blocked and enjoyed the data it finally got, or that it gave an error and didn't take any data at all. But if this is how it is, then ... that is how it is ;-) /Mads using alsa-lib-1.0.21-3.fc11.i586 alsa-plugins-pulseaudio-1.0.21-2.fc11.i586

[alsa-devel] Revised Patches for Samsung SoC PCM Controller driver
by Jassi Brar 14 Nov '09

14 Nov '09

Hello, (I have made a few modifications suggested for previous set of patches) Samsung SoCs S3C2450, S3C64XX and later versions have got PCM controllers which drive what the ALSA stack terms DSP_A/DSP_B formats. Since the S3C ALSA platform driver was named s3c24xx-pcm, which cause direct namespace clash with the new PCM controller drivers, it has been renamed along with some of its local symbols. First two of the following series of patches does that and later ones make ground for and add the PCM controller driver. regards.
