After upgrading to a 2.6.21 kernel (2.6.21-suspend2-r5) from 2.6.19 (2.6.19-suspend2-r3), my sound doesn't work any more. I am using the in-kernel drivers. With 2.6.19 I had no problems. After replacing SND_PCI_QUIRK(0x1179, 0xff10, "Toshiba", ALC861_TOSHIBA), with SND_PCI_QUIRK(0x1179, 0xff10, "Toshiba", ALC861_AUTO), (I found this in a ubuntu kernel update) in sound/pci/hda/patch_realtek.c, my sound works, but after about 30 minutes to 1 hour after I started mplayer, it hangs and repeats the last half second infinitly. Reloading the ALSA modules or '/etc/init.d/alsasound restart' doesn't help, the only way to fix this is rebooting. Nothing special in dmesg. It happened three or four times so far. It only crashes if I access the sound hardware, after a few hours without mplayer, sound still works great. lspci: 00:14.2 Audio device: ATI Technologies Inc SB450 HDA Audio (rev 01) lsmod: Module Size Used by fglrx 645532 11 wlan_tkip 11424 2 wlan_ccmp 7104 1 fuse 38164 0 tun 7968 1 vboxdrv 26884 0 wlan_scan_sta 11488 1 ath_rate_sample 11936 1 ath_pci 86496 0 wlan 188516 6 wlan_tkip,wlan_ccmp,wlan_scan_sta,ath_rate_sample,ath_pci ath_hal 189456 3 ath_rate_sample,ath_pci 8139too 19936 0 ehci_hcd 27148 0 snd_hda_intel 15800 0 snd_hda_codec 205120 1 snd_hda_intel snd_pcm 59656 2 snd_hda_intel,snd_hda_codec snd_timer 17540 1 snd_pcm snd 37176 4 snd_hda_intel,snd_hda_codec,snd_pcm,snd_timer soundcore 5472 1 snd snd_page_alloc 7464 2 snd_hda_intel,snd_pcm ohci_hcd 18372 0 Reproducible: Sometimes Steps to Reproduce: 1. Install suspend2-sources-2.6.21-r5 on toshiba satellite A100-649 2. Patch kernel as described above 3. Sound hangs after 1h with mplayer
Does it hang after suspend or after normal boot? Can you please check if it happens also with gentoo-sources?
It hangs after a normal boot. I didn't suspend since I updated to 2.6.21. I'll try gentoo-sources tomorrow.
sorry, but currently i am unable to reproduce it - not with 2.6.20 and not with 2.6.21-suspend2-r5 :(
Can we close this for now?
