[alsa-devel] Alsa: USB Class 2 Audio soundcard device disappears suddenly
by Joao Bonina 31 Jul '12

31 Jul '12

Hi, I'm using an USB Class 2 Audio DAC (basically a soundcard) with my Linux box and MPD software. It works great when playing files stored in a remote share, but when playing files from an USB pen, it stops playing in a few minutes. Mpd.log shows this: Code: Jul 30 13:03 : output: "USB" [alsa] failed to play: No such device Jul 30 13:03 : output: closed plugin=alsa name="USB" ALSA lib pcm_hw.c:1401:(_snd_pcm_hw_open) Invalid value for card Jul 30 13:03 : output: Failed to open "USB" [alsa]: Failed to open ALSA device "hw:0,0": No such file or directoryIt seems to be somewhat related to the USB bus not being able to cope with both PCM streaming to the soundcard and reading from the flash pen simultaneously, I guess. So, anybody faced this issue previously and can provide some hints to solve this? MPD is 0.17, kernel is 3.2.17, alsa-utils is 1.0.25.

The file is attached :-) Phone works (under winxp) without any driver (speaker and microphone), but driver is needed for buttons...

[alsa-devel] [PATCH] es1688 - freeup resources on init failure
by Fengguang Wu 30 Jul '12

30 Jul '12

> > err = snd_es1688_init(chip, 1); > > if (err < 0) > > - return err; > > + goto exit_release_dma; > > > > /* Register device */ > > return snd_device_new(card, SNDRV_DEV_LOWLEVEL, chip, &ops); > > + > > +exit_release_dma: > > + free_dma(chip->dma8); > > +exit_release_irq: > > + free_irq(chip->irq, chip); > > +exit_release_region: > > + release_and_free_resource(chip->res_port); > > +exit: > > + return err; > > You can simply call snd_es1688_free(chip) instead of a bunch of > labels. That is, all goto's can be "goto exit", and > > exit: > snd_es1688_free(chip); > return err; snd_es1688_free() will call snd_es1688_init() which in turn use the uninitialized spin locks and other data. So I end up with the below patch. snd_device_new() could also return errors and will be handled in the same way. I don't have the hardware, however tests show it at least fixed the boot time irq mismatch warnings. Daniel, thanks for your initial implementation and please kindly confirm the below 3rd version :) Thanks, Fengguang --- es1688 - freeup resources on init failure This will fix the following oops: [ 6.169981] genirq: Flags mismatch irq 5. 00000000 (ES1688) vs. 00000000 (ES1688) [ 6.170851] Pid: 1, comm: swapper Not tainted 3.5.0-00004-gceee0e9 #14 [ 6.170851] Call Trace: [ 6.170851] [<c1062237>] ?

[alsa-devel] [PATCH v2 0/4] Use dma_mmap_coherent to support IOMMU mapper
by Hideki EIRAKU 30 Jul '12

30 Jul '12

There is a dma_mmap_coherent() API in some architectures. This API provides a mmap function for memory allocated by dma_alloc_coherent(). Some drivers mmap a dma_addr_t returned by dma_alloc_coherent() as a physical address. But such drivers do not work correctly when IOMMU mapper is used. v2: - Rebase on fbdev-next branch of git://github.com/schandinat/linux-2.6.git. - Initialize .fb_mmap in both sh_mobile_lcdc_overlay_ops and sh_mobile_lcdc_ops. - Add Laurent's clean up patch. Hideki EIRAKU (3): ARM: dma-mapping: define ARCH_HAS_DMA_MMAP_COHERENT media: videobuf2-dma-contig: use dma_mmap_coherent if available fbdev: sh_mobile_lcdc: use dma_mmap_coherent if available Laurent Pinchart (1): ALSA: pcm - Don't define ARCH_HAS_DMA_MMAP_COHERENT privately for ARM arch/arm/include/asm/dma-mapping.h | 1 + drivers/media/video/videobuf2-dma-contig.c | 18 ++++++++++++++++++ drivers/video/sh_mobile_lcdcfb.c | 28 ++++++++++++++++++++++++++++ sound/core/pcm_native.c | 7 ------- 4 files changed, 47 insertions(+), 7 deletions(-)

[alsa-devel] Immediate underrun with PulseAudio ALSA plugin when PA and ALSA buffer sizes differ
by Matthew Gregan 30 Jul '12

30 Jul '12

I'm investigating an issue in Firefox's audio code when the PulseAudio ALSA plugin is in use. I posted about this on pulseaudio-discuss last week (http://lists.freedesktop.org/archives/pulseaudio-discuss/2012-July/014091.h…), but I hoped I might have more success here. Firefox requests a particular latency (100ms, 4410 frames at 44.1kHz) via snd_pcm_set_params. Inside the plugin (pcm_pulse.c:pulse_hw_params), that value is used to set up buffer_attr. When the PA stream is connected in pcm_pulse.c:pulse_prepare, PA may configure the stream with larger buffer_attr values (e.g. because the minimum sink latency has increased over time due to underruns on the server, or because the sink hardware doesn't support lower latency), but this isn't reflected in pcm->buffer_attr or higher layers in ALSA (i.e. pcm->buffer_size is not updated). The problem I'm faced with is that there doesn't appear to be a way to detect and handle this issue at the ALSA API level, and requesting a too low latency results in broken audio playback rather than a PCM setup failure or a larger buffer than requested being used. In the case of the PA server's minimum latency increasing over time, this also means that a stream that was configured and running correctly may break while running if PA increases the minimum latency above what the PCM was originally configured with. I've attached a simple testcase that uses snd_pcm_wait, snd_pcm_avail_update, and snd_pcm_writei. Run it with a latency argument specified in milliseconds on the command line. For my local machine, 55ms works and 54ms fails immediately like so: snd_pcm_wait wakes snd_pcm_avail_update returns 4410 snd_pcm_writei writes 4410 snd_pcm_wait wakes immediately snd_pcm_avail_update returns -EPIPE (Note that when I reported this on pulseaudio-discuss, my server's minimum latency was 45ms, and now pacmd list-sinks | grep configured\ latency reports a minimum latency of 56ms) I'd expect to see one of the following behaviours instead: 1. PCM setup fails due to requesting a too small buffer. 2. Buffer is silently raised during setup and snd_pcm_avail_update requests the correct number of frames. Presumably this could be achieved by having the PA plugin report valid values from pcm_pulse.c:pulse_hw_constraint, but I'm not sure how to query the necessary values from the server. This also wouldn't address the problem where the buffer_attr changes over time, and I'm not sure what to do about that case. Thanks, -mjg
