[alsa-devel] [RFC PATCH v3 0/3] ep93xx i2s audio
by Ryan Mallon 08 Jun '10

08 Jun '10

The following patch series adds support for i2s audio on the ep93xx, with the Snapper CL15 used as an example implementation. This version fixes a number of things from the previous round: - Removed unused #defines - Set symmetric rates for the cpu dai - Fixed the sdiv/lrdiv calculation loop - Moved the cpu dai registration - Removed empty ep93xx_pcm_prepare callback - Fixed enable/disable when both capture and playback are running Capture still does not work. The dma is running, but the captured data is all zeros (tested used arecord and loopback). I have a 2.6.20 kernel with ep93xx i2s audio working an capture works there on the same hardware. I have spent sometime looking into this, but can't see the problem. Would appreciate if someone can lend some insight as to what I have done wrong.

[alsa-devel] No mixers on ATI RS780 Azalia
by Jan Engelhardt 07 Jun '10

07 Jun '10

Hi, I have here a Samsung 320MXn2 monitor/mainboard (typical x86_64 environment) where I cannot get sound output to the internal speakers working. To start, there seem to be two sound cards: lspci/lspci -n: 00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) 01:05.1 Audio device: ATI Technologies Inc RS780 Azalia controller 00:14.2 0403: 1002:4383 01:05.1 0403: 1002:960f /proc/asound/cards: 0 [SB ]: HDA-Intel - HDA ATI SB HDA ATI SB at 0xf0500000 irq 16 1 [HDMI]: HDA-Intel - HDA ATI HDMI HDA ATI HDMI at 0xf0110000 irq 19 The soundcard responsible for the internal speaker is the 01:05.1/"HDMI" one. Under Windows XP, I see the following mixer elements for it: * Master Volume * Wave * SW Synth * CD Player Subsequently, there is sound (once I bump the volumes on these). However, in Linux up to including 2.6.34, I only see a single mixer element: * IEC958/S/PDIF mplayer etc. all successfully write to the device, but since there are not any further mixer controls, I can't unmute the essential channels. alsa-utils is version 1.0.21, from openSUSE 11.2 x86_64. Any help is appreciated. Thanks, Jan

[alsa-devel] [PATCH] ASoC: tlv320dac33: Add support for changing upper threshold
by Peter Ujfalusi 07 Jun '10

07 Jun '10

Upper threshold is used in mode7 of DAC33. Instead of hard wired UTHR, add control to change the upper threshold value. Changing upper threshold is not allowed when the playback is already running, since wrongly timed change in the UTHR can cause problems with the codec. With this control the length of the burst in mode7 can be changed.

[alsa-devel] 2.6.34-rc: sound hungs (ice1724)

Hi Takashi Could you please help me how to debug an issue. Sometimes soung hungs, it happens few days (up to a week) after boot. I have no idea how to reproduce it or how to debug it. That's why it is very hard to bisect, I have not tried, the better way should exist. The problem appeared somewhere after 2.6.33. Card is M-Audio Revo 5.1 (1412:1724). After it hungs ALSA continues to play last sound frame forever. When I try to play something else playing frame changes. Only reboot heals it. rmmod hungs at INFO: task rmmod:30356 blocked for more than 120 seconds.
