[alsa-devel] Codec "virtual multiplexer" representation
by Petr Kulhavy 24 Feb '16

24 Feb '16

Hi, I'm writing an ASoC driver for the TAS5721 amplifier. This 2.1 amplifier provides a complex configuration of the audio channels (3), PWMs(4) and output(4) mappings. However only few (about 6) configurations really make sense. I'm trying to model the output configurations in ALSA. In order to avoid a complicated set of switches and multiplexers I would like to add just one multiplexer like control which selects one of these 6 output configurations and a callback function which sets the proper registers accordingly (there are 5 affected registers). Is there a way to create such a "virtual multiplexer" in ALSA? Thanks Petr

[alsa-devel] Fwd: Lenovo Y700-17ISK notebook - multiple issues
by Aljosa 24 Feb '16

Hello, advised by one of the kernel developers - I'm reporting you the problem nr.2 from the below link. Best regards, Aljosa -------- Original Message -------- Subject: Lenovo Y700-17ISK notebook - multiple issues Date: 2016-02-21 11:18 From: Aljosa <aljosa(a)cromalternativemoney.org> To: jkosina(a)suse.com Reply-To: aljosa(a)cromalternativemoney.org Hi, please excuse me if I contact you in this way - I found your email by googling "Lenovo" inside the Linux kernel mailing list archive. Few days ago I purchased a new Lenovo Y700-17ISK notebook, and after installing "current Ubuntu 16.04 daily build" I'm facing some issues which I think are kernel related: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1547934 Consequently, I would like to inform kernel developers about these problems. If you are not the right person to contact on this subject, please route this e-mail to whomever can help me or let me know who to contact - thank you very much in advance. Best regards, Aljosa PS. I have just tried freshly released kernel v4.5-rc5-wily (http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D), and with it my wireless connection now works, but there are still plenty problematic lines inside DMESG output.

[alsa-devel] [BUG] [REGRESSION] [BISECTED] -rc1 breaks audio over HDMI for i915
by Martin Kepplinger 24 Feb '16

24 Feb '16

The following change: 788d441 ALSA: hda - Use component ops for i915 HDMI/DP audio jack handling breaks audio over HDMI on my snd_hda_intel laptop. It is the first bad commit. This was merged for -rc1 and isn't fixed until now, so I got nervous. There are no errors in the log that stand out. I'm no sound or alsa developer, and just reverting it isn't easy since there is stuff depending on this. I'm happy to test possible fixes and hope v4.5 not to ship with such a big regression ;)

[alsa-devel] ASoC: simultaneous start of input/output channels
by Jonah Petri 24 Feb '16

24 Feb '16

Hello! Our application is very low-latency full duplex audio on a Freescale SoC. ALSA is configured with 2 64-frame buffers, with DSP happening on a realtime user thread. With small buffer sizes, we're obviously very tight on timing, and I've run into an issue which seems architectural in nature, and seemingly is worthy of consulting the list. What we're seeing is a large temporal latency between the DMA completion IRQ for the audio input DMA and audio output DMA. This delay is on the order of 200 microseconds, but also somewhat variable (ok, "large" is relative here, but it matters to us!). In the ideal case, these two interrupts would be perfectly aligned in time, allowing us to run DSP for the full buffer's duration. However, since the interrupts are offset by about 20% of a buffer, we effectively lose that time for our DSP. And, since the timing is variable, and we're in a realtime application, this produces scared engineers. Working backwards from the hardware drivers, I see that snd_soc_dai_ops's trigger callback is used to start and stop the DMA. The fundamental "start" action comes down to a single register write which can easily start both input and output streams in the same write. However, it seems that the snd_soc_dai_ops does not provide for simultaneous start of both input and output streams. Tracing back through the kernel interface and into user space, it seems that starting both the input and output streams necessitates two separate calls from userspace, which could explain the delay, and some of the variability in timing. My question is: * Did I miss some API or technique which could allow simultaneous start of full duplex streams? * If not, I would certainly appreciate advice on where we could fit this into the existing architecture! We would be glad to do the kernel work to make this change, as this capability seems generally useful! Thanks much for any help, Jonah
